I recently got the Gtx 770 2GB ($310 with three free games via Nvidia) a few months back and have enjoyed it. Assassins Creed 4 runs around 40-55 FPS with ultra everything in settings, 1080p, 4x MSAA and physx particles on normal. Physx Particles on extreme caused it to dip under 30 fps in boat fights and around campfires. I have it slightly overclocked but not much. Having physx support is pretty awesome though. Bioshock Infinite also ran over 60 fps 98% of the time.
I got it on the recommendation that I wouldn't need the 4GB of ram as the kinds of games that will need that much at 1080p/1440p are years off. Although I'm not sure that is a true statement anymore. I really hope I didn't fuck up by not spending the extra $50-$60 for the 4GB.
