Hey guys, my names Darius and I'm back again to build a new PC for general use and gaming. The games I will play are WoW, Guild Wars2, BF3, Call Of Duty, Diablo, etc 
I have a pretty tight budget of £600-630, preferably closer to the £600 mark, but £630 is the absolute max.
I've tried adding components to the basket myself and I just couldn't decide on what components to get in the end so here I am!
I already have Two monitors, keyboard, mouse and windows 7.
There's a few things I'd like in the build:
i5 processor with the overcloccking capabilities
Nvidia graphics card that will let me use 2 monitors at once (I hate alt-tabbing!)
A good motherboard that will allow me to upgrade overtime, I'd also like the option of using two Nvidia graphics cards at once (SLI? Not sure if that's what it's called haha)
Thanks in advance for any help!
