Hi there, I want to play a game like GW2 on ultra for as low as price as possible, Ideally I would like a PC with 8gb of ram, an Nvidia GTX 660+ and at least a quad core processor of 3.1ghz, I already have a Amd Anthlon II X4 3.1ghz incase that will lower the price? I don't know much about building PCs or anything really, I just want to play some games at Ultra for as low a cost as possible, I live in the UK incase that is relavant, thanks in advance.
