Gaming computer build

[LouieG02]

Heyy guys, just looking for a little advice on building my own computer, im into FPS games like call of duty, BF3, i also like Skyrim and RPG games, And Gmod, im wanting a computer that can run at high/medium settings, dosnt need to be ultra, i will be playing at 1920x1080, i have keyboard, mouse and a monitor, all i need is the insides to be decent enough to run high-ish games, and the bigger titles,
I have OS, Keyboard and mouse, Monitor.

My budget is £350-400GBP ish if its possible let me know but the cheaper the better .
Heres what ive got so far.

always buy ram in twos. ram heat spreaders are standard for gaming these days. rather go for a corsair cx500m psu. the 660 isn't much more. get that instead.
