For this kinda set-up (Refering to the desktop computer) you could get a laptop that will dominate in 1080p gaming. Most laptops in this price range include a 880M, which is currently the most powerful mobile graphics available. Hell, you could probably SLI them, but you're not going to get as much performace as the desktop. You have to figure out what you value more. Mobility, or power.
I personally had to make this choice a little less than a week ago. Here's the company I went with... (http
/www.xidax.com/laptops), they also making gaming computers as well. The reason why i went with Xidax insead of Dell (Alienware) is because they offered a 3yr warrantee on all the parts of the laptop. That's unheard of in the laptop world. Let's say your battery goes bad because you keep it charged all the time, they'll replace it for free. Plus their customer service is bar none, the best I've ever dealt with. They answered all my questions, and then some. They didn't try to force me to buy the more expensive option (I was doing that anyways lol).
Another company you can try is (http
/www.ibuypower.com/) I had a good experience when I bought a laptop from them about two years ago. They offer really good prices, however their warrantee isn't as good as Xidax. I spent 2.5k on my laptop and I'm more than happy with the results. Personally, the reason why I went with a laptop instead of a desktop is because I deploy alot. Currently in the USAF, and I'm in Afghanistan right now. Plus, it's always nice to be able to take the laptop to any room of your home and hook it up to the TV. I use it as a "mobile gaming platform" for anything from PCSX2 (PS2 simulatior) to The Witcher 2/w a PS4 Controller. That's something I really value from a laptop.
Also, as far as liquid cooling goes. refilling it every 6 months is not a detrement for the performance you get, including overclockability. That 295X2 absolutely needs to be liquid cooled. Powercolor came out with a air cooled solution not too long ago, but it's not stable at all. Stick with what you have, those specs will build an amazing desktop for that price. Also, if you can hold out, I would suggest waiting until Skylake comes out. It's going to include DDR4, which is supposed to be a step up power wise from DDR3, and more power efficient. Also, I would suggest RAID 0 (Getting two SSD's and putting them in that coniguration) for a massive speed boost. Just don't put ANY important data on the raid array, otherwise it'll be lost if one of the SSDs fail.
