One thing people are not pointing out with these and the last few drivers with AMD.
THEY DONT PLAY SKYRIM! This is but one game i know, but the fact they have made no effort to cure the artifacting in this game shows they dont care. I bet with new releases there will be more games with such unplayable glitches.
Sure you can roll back and forth for games but do you really want to?
I really wanted the 7850 and tried 3 different cards but my computer just hates it lol, it will not work in my pc for whatever reason. Its not CPU limets as it wont run any better when i OC, surely from 2.6-3.4 it would see more fps? But it doesnt.
I know im one of the few with serious issues with this card, ive put it down to MB not supporting it. But the fact remains the new drivers speed up some games but break others, atleast Nvidia keep everything together.
Im sure at the end of the day the 7850 and 660 will play both games about the same if you dont watch the fps meter, but the 660 will play more games (skyrim).
So if i didnt play skyrim and had a better MB id go 7850.
If i dont wanna risk not being to play some games and suffer a few less fps id go 660.
