I posted another thread but it became inactive so I'll repost. I have around 150 for a GPU and don't know what to get someone recommended this http://www.overclockers.co.uk/showproduct.php?prodid=GX-185-MS&groupid=701&catid=56 but I noticed some of the 7850s are more expensive would these out perform the recommended GPU?? My final question is that I need a PSU for my new system and don't know how much wattage to get and someone to estimate one for me. My specs:
Cpu-Fx 6300
CPU cooler-cm hyper evo 212
Ram-patriot viper 3 black mamba 8 GB 1600mhz
Mobo-asrock 970 extreme 3
Hard drive - half a tb (I plan on 1tb)

So even though some 7850s are more expensive than the MSI 7870 the 7870 will still out perform them??
Also would anyone know what settings this card will run b3 dayz diablo 3 crysis 3 etc at on 1080p/720p also would I be able to pick up a 500 - 550 w for about £40?
