Well, I'm getting roughly $500ish (£320ish) and am looking to upgrade my PC, mainly Graphics and PSU. My specs (I have a 300W PSU right now) More info about my mobo I am currently looking at buying: http://www.ebuyer.com/product/227181 http://www.ebuyer.com/product/200490 however am uncertain whether everything will work etc etc since I'm quite noobish when it comes to hardware. Any advice, changes or any other comments? I'm really looking for stuff that will play all Source Games at high settings, as well as play the new Call of Duty when it comes out etc. halp.
