4K gaming? No sweat, with its AMD dual-Radeon R9 295X2 GPUs configured in quad Crossfire mode, it pumps out the pixels on cue. Just watch your energy bill, this Corsair H105 closed-loop, water-cooled mosasaurus is as quiet as a mouse but runs from a 1500W Silverstone Strider ST1500 power supply. Needless to say, it arrived on a pallet.Booting up this monster rig, I’m well aware there are few who have the resources to equip themselves with such high-end gaming hardware. This may be last year’s model that fetched £4,000 at the time but I’m not complaining, as suddenly I’m a member of an elite club.But for how long? I suspect the financially insecure won’t be closed out of this clique indefinitely as the Viewsonic VX2475Smhl-4K monitor retails at a reasonable £329, and all you need is the kit to run it, which brings me back to where I started.The GPU will always be the limiting factor and at 4K you can almost smell the cheaper ones burning and falling over. You’ll also need to make sure you are compatible. HDMI 2.0 has only recently appeared on graphics cards with Nvidia’s GTX 980/970 being the first. So if you’ve a capable GPU, you’ll most likely be relying on a DisplayPort 1.2 connection to drive the 4K 50/60Hz resolution image.

Earlier incarnations of HDMI weren’t up to the 17.28Gbps bandwidth this hi-res, fast refresh output demands. If you waited for HDMI 2.0 – now featuring on most recent 4K sets – then it can handle up to 18Gbps.However, you’re still likely to run into headaches if you were hoping to use a DisplayPort to HDMI lead to connect your GPU to work with a 4K telly, as these converter cables don’t support the bandwidth either. So, it looks like a choice of buy the latest Nvidia GPU or get 4K capable DisplayPort monitor.If you’re a clever clogs, you might try following the advice of Geforce forum poster Thruput who made an adapter using an Explore EP963E DP 1.2 to HDMI 2.0 converter chip – though it seems he has some expertise in such matters.He told us he bought the development board from Explore in China for $300 and it worked out of the box. Effective, but not exactly cheap.There is another alternative. If you’ve not invested in a 4K telly yet but have this in mind as your main gaming display, then Panasonic does make 4K TVs with DisplayPort 4K 50/60Hz connectivity (as well as HDMI 2.0, of course), but the cheapest appears to be the 50-inch TX-50AX802B which will set you back about a grand.

Incidentally, I asked Startech if it had anything at 60Hz in the offing, the reply was, "we are actively working on a DisplayPort 1.2 to HDMI 2.0 adapter as well as a DisplayPort over USB-C to HDMI 2.0 adapter. Once we launch the adapter we will start to explore cable versions." Encouraging, but don’t hold your breath.Recording at 4K is just becoming viable (watch this space) with options like Geforce Shadowplay but you’ll need a whole lotta RAM if you want to do any serious editing.The GX700, shown off by the company ahead of the IFA conference in Berlin, connects to an external cooling system that pumps water through the notebook to cool off its overclocked Intel Skylake CPU.To call the GX700 a "laptop" is more than a bit of a stretch. Aside from being a sizable 17-inch notebook, the GX700 would need to plug into the cooling box via a dock connector. Presumably the notebook itself can be disconnected, though that would of course require running the system at a lower performance level to keep temperatures down.Other promised features in the water-cooled notebook include what Asus called the "latest Nvidia GPU" with support for 4K resolutions on the 17-inch screen.

One can’t imagine that what will surely be a fairly expensive notebook – which also requires an external cooling unit – to be a huge seller, but if Asus‘ aim was to grab headlines and get some attention for its other, more portable and reasonable Republic of Gamers (ROG) gaming products, then the Taiwanese PC builder certainly accomplished its mission this week.Rising Dragon Xiaomi is reported to be revving up the tanks to park on Apple’s lawn with the launch of a laptop.The new lappie is rumoured to be a high-end 15" notebook pitched at the MacBook Air, but at half the price. Rumours of the project have leaked to Bloomberg from component suppliers, who say that the company has been talking to Samsung about supplying memory and possibly displays.Xiaomi has the deep pockets to take on the highly competitive, shrinking and thin-margin computer business. It has raised $1.4bn from investors and has grown to be the number-two smartphone in China on a growth curve that will soon take it ahead of Apple for the top spot.

Taiwanese website Digitimes claims that the new laptop will eschew Windows for Linux. This is a move that might point to a port of the Xiaomi MIUI user interface used on the phones to the laptop and would be consistent with the company’s plans to be a source of content as well as hardware.It’s believed that Xiaomi has been talking to manufacturing giants Inventec and Foxconn Electronics about the project.The move into computers would be a new front for the phone company, which has just launched in India and is about to start selling phones in the US and Europe. Review Asus’s new Chromebook Flip isn’t the first touchscreen Chromebook we’ve fondled here at The Register. That accolade belongs to the Lenovo N20p. But since the N20p has been discontinued in the UK, Asus needn’t worry about its new convertible being overshadowed by it.Of course, the fact the N20p lasted less than a year before Lenovo yanked it may also suggest machines like it and the Flip are answers to a question nobody is asking.My first impression of the Flip was how surprisingly small it is. That’s largely down to it having a 10.1-inch display rather than the more usual 11.6- or 13.3-inch affairs found in other Chromebooks.

The upside to having a small screen is how diminutive the whole device is. The Flip weighs a piffling 890g and is only 15.6mm thick. Laptops don’t come much thinner or lighter.The downside is that there is a reason laptops don’t come this small or thin. When they do, they are – or were – called netbooks. Whether or not you think this is the right size for a Chromebook depends on what you plan doing with it.Considering the inherent limitations of Chrome OS – it’s a thin web client and not a whole lot else – do you need a larger screen? Possibly not. Though if I was buying a Chromebook, it would be because I wanted a cheap laptop; in my book that means at least 11.6, but preferably 13.3 inches, between the corners.If you plan on replacing Chrome with a Linux distro then a larger screen is probably what you’ll want. On the subject of Linux, I spent an entire afternoon trying to get Linux onto the Flip using Crouton and failed utterly.The Flip’s screen is a pretty good one. The gloss-finish IPS panel is colourful and bright and viewing angles are impressively robust. The resolution of 1200 x 800 is, however, nothing to get excited about.

Should the resolution be higher? In this age of reasonably affordable Android tablets with 1920 x 1200 displays, the case could be made. Still, I have say that, in terms of clarity and sharpness, the Flip’s display looked just fine to my eyes. There’s quite a lot of bezel on show around the screen though, which rather spoils things. The Flip’s lid wouldn’t have had to be made all that much larger to fit an 11.6-inch panel into it.While many Chromebooks are made of cheap and nasty plastic, the Flip is a smart, all-metal affair. With its brushed metal casing, it looks and feels rather like a third-scale MacBook Air, and that is praise enough.The screen hinge is reassuringly robust, important for something that has to hold its position in either tent, stand or tablet mode, as well as when it’s being tapped and poked in laptop form.The keyboard and touchpad are impressive feats of miniaturisation too. The latter measures a mere 85 x 45mm but is still eminently usable, and the same is true for the approximately 85 per cent sized keyboard. The Flip’s keyboard is one of the most solid I’ve ever encountered on a cheap laptop.

A brace of loud and tuneful speakers are built into the underside of the keyboard deck, making this one of the better sounding Chromebooks money can buy.Peruse the Flip’s curved sides and you’ll find two USB 2.0 ports, a micro HDMI socket, 3.5mm combo audio jack and a microSD card slot. There’s also a power switch and a volume rocker on the front left, along with a couple of status LEDs. I found the on/off button rather too easy to touch by mistake.Wireless connectivity is handled by the 802.11ac Wi-Fi and Bluetooth 4.1 radios. During my tests the Wi-Fi left something to be desired when it came to keeping coznected in places I know to have questionable but usable reception.Asus has forgone Intel chippery in favour of a 1.8GHz Cortex A17 quad-core Rockchip RK3288 SoC with 4GB of RAM and Mali T764 graphics. That means what we have here is a Chromebook running on ARMv71, rather than the more common x86 architecture, the odd Exynos-powered Chromebook from Samsung and the HP Chromebook 11 being the exceptions.What does this mean in the real world? Poorer performance, better battery life and some programme compatibility issues under Linux, assuming you can get it to work.Running browser benchmarks like Google’s Octane and Mozilla’s Kraken, the Flip returns amongst the lowest scores I’ve ever seen on a Chromebook. Thankfully, those results don’t actually have much of an impact in the real world. The Flip doesn’t feel any slower in everyday use than the Lenovo N20p, a machine that beats it soundly in every synthetic benchmark test.

The Flip’s battery life is very impressive, the best of any Chromebook I’ve tested. Loop a 720p MP4 file and the 31Whr battery will keep the lights on for 12 hours. In mixed use I was only charging the Flip every three or four days. The Flip doesn’t just have more endurance than any other Chromebook I’ve used, it has more than pretty much any other laptop I’ve used.Being a Chromebook the Flip is all about the cloud, so you only get 16GB of storage, or just under 10GB after system requirements. Having a microSD card slot means that adding extra storage isn’t a problem, though.How well does Chrome OS work on a touch screen? So so. The layout is the same as on a regular laptop so there’s no real touch optimisation to speak of. At least the screen resolution doesn’t make everything too small to tap and the panel is very responsive to the touch.The panel selector makes the selection of web apps easy using the touchscreen
To my way of thinking, touchscreen convertible Chrome devices like the N20p and Flip are really more about the convenience of holding them as tablets rather than using them as tablets. As a touchscreen UI, Chrome can’t hold a candle to Android. Or Windows 10. That being the case, and the Flip only having a 10.1-inch display, why not just buy a 10.1-inch Android tablet and a Bluetooth keyboard? Why indeed.

The last, and biggest, issue I have with the Flip is price. In the USA the Flip is a $249 (£160) machine (for the 2GB RAM version, $279 for the 4GB) but in the UK you’ll need to part with £249. Granted, that price includes VAT, but I still can’t get over the feeling that in Blighty the Flip should really carry a sticker price under £200 because that sort of money will also buy you a HP Stream laptop with a 13.3-inch touchscreen and Windows 10.The £230 HP Stream x360, the most obvious competition for the Chromebook Flip, seems to have been discontinued in the UK. Do I detect a trend? Maybe small convertibles just don’t sell no matter what the operating system. But you can still find it in the retail channel and it has an 11.6-inch screen and, again, it runs full-fat Windows.I’m in two minds about the Flip. I like the size, the build, the style, the battery life. The keyboard, speakers and display are all rather good too. But for the money you can get Android tablets with the same size but higher resolution screens and bigger, more powerful Windows 10 machines.

Yes, the Chromebook boots faster and is more secure but the HP Stream-series laptops are far more versatile. As it stands, the Chromebook Flip is a nice bit of kit that either needs a bigger screen or a lower sticker price to be wholeheartedly recommended. The batteries in question are dated between May 2011 and July 2012, and were offered as spare standalone batteries. In some cases, Fujitsu says, the batteries may also have been installed post-sale as replacements.VMworld 2015 VMware’s trying to put itself into the Windows desktop management business with its AirWatch mobile device management and identity management products.AirWatch is best known as a way to manage and deploy apps to mobile devices, based on user profiles that determine what users are allowed to run and/or the resources they are allowed to access. At VMworld 2015 today, VMware demonstrated a project called A2 that allows AirWatch to do the same for Windows 10 desktops.
