This build on PCpartpicker was a bit off, and you can find all of my bits on Scan for about £900. I already had a keyboard, mouse and 1080p monitor. So far, it's running EVERYTHING I throw at it at absolute max, 1080p and 60FPs (Cept Planetside 2 in really populated zones, seeing about 40FPS). It runs cool, quiet, and very fast indeed.
The GFX card's monstrous too. It runs super cool and quiet, and it looks awesome in the case.
