Something that has to do with the cards being built so gimped out that it doesnt even utilize the 3GB like its supposed to.... i really would suggest going with the 2GB cards. Unless you plan on going 1440p or 1600, the 660ti 2gb will do you good at 1080p. if you want more vram i suggest going with the 670 which utilizes ALL of its 2GB VRAM compared to the 660Ti which doesnt, 256 bit memory bus is supposed to be the "symmetrical"/"normal" design for NVidia, but NVidia has had history of sneaking in a "192 bit memory bus" (like in last years 550Ti).
Well I decided to go with a 2GB GTX 660 TiOC, and use one of my GTX 460s as a dedicated PhysX GPU.
Stayed with the same ASUS M5A97 r2.0 mobo, though I won't be able to run SLI without modding my OS.
I also upgraded to a bronze 80 certified 900w PSU, just to be safe.
WIth the trade in of the two HD 7770s, it only cost me another $25.00.
Seems to be working well so far, and having physx is always nice.
