I HIGHLY recommend the 7850, got one for my brother and its a BEAST + OCs. But I don't think it's the best buy this month, I would go for the 7950 for a little bit more, or a 660/660 ti. You can get them real cheap and they are MONSTER SLI cards. The 660 has an amazing boost and so does the TI.
I have a 660 OC, if I could rebuy today I would go for the 7950 and OC then get ready for CFX:D next year.
EDIT: No BS my bro uses a i5 750k @ 3.8ghz on air, runs the 7850 perfectly (Planetside 2 even runs great). That 760k will be plenty for any card out there right now. However I can't speak on the revelations to come before the end of the quarter Edited by LDV617 - 10/19/13 at 3:21pm
