I'm running a pair of GTX 275's in SLI and am looking to make a worthwhile upgrade, that will keep me running games on ultra high for a few years like these things did. Would a single GTX 660 give me a large performance increase? I'm also not sure if my rig would bottleneck it. Here's my specs, I'd really appreciate any advice on this:

Intel Core i7 920 @ 2.67GHz
6GB DDR3 RAM @ 1600MHZ
Two 640 GB WD Caviar Blacks in RAID 0
NVIDIA GeForce GTX 275 x 2 in SLI
ASUS P6T motherboard

Your original choice EVGA 02G-P4-2678-KR GeForce GTX 670 FTW 2GB has 1.49X the performance of two GeForce GTX 275 in 2-way SLI mode.

The MSI N660 Ti PE 2GD5/OC GeForce GTX 660 Ti 2GB has 1.3X the performance of two GeForce GTX 275 in 2-way SLI mode.

Is that from the nVidia website? I'd estimate a very small performance gain from a GTX660 or GTX660 Ti. Your SLI setup is probably quite close in performance to a single GTX480 / GTX570 / HD6970 / HD7850 if that's any help. If you need more graphics muscle, you'd want to step right up to a GTX670 for a noticeable improvement, or wait for next year's models.

I think I'm gonna go with the 670, as a 1.3x increase from the 660 really isn't worth hundreds of dollars to me. Go big or or go home, right? Within reason anyway.

Thanks for the advice guys.

Another benefit is that you'll have more performance with lower power consumption and heat than your current SLI setup.
