So I've been lurking these forums for a few weeks learning as much as I can and now I finally have the money to build my new system
It's mainly for gaming, and I'd like it to be as futureproof as possible.
I was thinking something along the lines of:
I haven't included a mobo as my knowledge is rather lacking in that area so that is where I need the most help (Also xfire/sli support would most probably be neccessary). My overall budget is around £750-£780, but preferably cheaper so I have more left over for games etc
As far as GPU is concerned it's hard to decide between the 4870 1gb and a 260, or possibly even a 4870 512mb (what would be the performance gains for a 4870 1gb over the 512mb version?) I'll be using my old dvd drive so no need for one, but is there anything else I'm missing as this is my first build?
