I've been looking round a lot and this is the build I've came up with, with a budget in mind
AMD Phenom II X4 965 BE (going to overclock to 3.8ghz)
Samsung F3 spinpoint 1tb (always looking for deals and may change if there is one of same quality on offer)
Corsair Vengeance 2x4GB 1600mhz
Gigabyte 7850 2gb OC
Asus M5A78L-M/USB3 Motherboard (not sure about this either, any suggestions would be appreciated)
OCZ 750w/ OCZ 650w/ Corsair enthusiast v2 650w / 520w Antec Neo eco (not sure which, is you have any other suggestions, they would be appreciated)
Antec Three Hundred Midi case / Bitfenix survivor
I'm not to bothered about crossfire, so the motherboard and psu need not have crossfire capability. Would this run current games well at 1920x1080? Any improvements you think i should make?
