I am in the exact same boat you are. I am gaming at 1080p now, but looking to go either 1 high resolution monitor or surround in the future. I am getting 2 4GB galaxy 670s. I'm well aware of all benchmarks that show the 7950 competing with a 670 for less $$$ but I had a bad experience with AMD and honestly, I want to go nvidia. They seem to do better in games that I like to play anyways. Not saying it's a bad card, but I'm going to stick with the company that hasn't let me down.
The Galaxy 4GB is $429 with a rebate of $20, bringing the cost down to $409.99. You get Borderlands 2 (which I am going to buy anyways) so that allows me to put the $60 I was going to pay for it towards a 670. Then, I'll buy another Galaxy 4GB 670 and I get a 2nd copy of Borderlands which I'll sell for $60, essentially putting the price of the 2nd card down to $360. With all that figured into the equation, these cards are going to cost me $350 each. That's an amazing deal.
I definitely wouldn't go 680 for the extra money. I thought about it too but it only averages 5 or so FPS higher than the 670 in most games and the 670s scale REALLY well in SLI. I've seen benchmarks where the 670s in SLI beat 680s in SLI. AMD is a solid choice, but, like I said, I've had some bad experiences with them. I'm sure I'd love a 7950 or 7970 if I got one, but I have more trust in nvidia. Plus, until AMD has something as dramatically different as physx in their back pocket, I'll never go to AMD. That video with Physx and Without Physx in Borderlands 2 is a staggering difference. Sure, only a few games actually use it correctly, but Borderlands 2 is my most anticipated game of the whole year and I want to experience everything!
