It's not a bad build, I'd personally opt for the 6gb 1060 which can be had for £30 more than a 4gb 480 although the 1060 can't be sli'd I don't think that psu would be much good for powering 2 cards anyways.
I'm a hardcore PC gamer and I am really intrigued by this. I grew up with Nintendo and I'm always hoping they can knock out another homerun like they did with the wii (I hated the wii but it sold like crazy).
