Yeah, I was pretty sure the 7950 didn't stack up to the 670, but couldn't be bothered to go digging - still a decent card though. The 7970 is a closer match, and the GHz edition out paces the 670 and competes with the 680.
Again, at 19x10 all of the above will serve you well.
BTW, I don't buy the argument that AMD cards are better because they offer more VRAM - they seem to need the extra memory to compete. Whether this is a throwback to the crappy memory controller performance shared by their CPUs... I don't know, but this isn't a fanboy argument - I'll quite happily swap between AMD and Nvidia when upgrading - just get the most for your money.
Before you judge a man, walk a mile in his shoes; after that, who cares?! He's a mile away and you've got his shoes!
