So you seem to contradict yourself.... Claiming its a driver issue, then saying AMD drivers are superior. Which is it?
Let me guess your gonna change your story again and say "Its a beta that's the real problem"
Let me stop ya there. We are less than two weeks away from launch, any increase you think AMD is gonna pull out of their hat, Nvidia has the exact same time to do so. So assuming performance will be better upon release is a huge leap of faith.
I go by numbers and as it stands right now 7950 is not superior in the game the OP wants to play. Sorry.
