The only difference I can spot is that the 660ti has 3gb of memory and that the GTX 670 had a greater memory interface. Does that matter? The price is only 40 bucks apart so I dont mind getting the GTX670 but I'm only going to get it if it has a better performance than the GTX 660ti. What do you guys think? Get the GTX 660ti or the GTX 670?
The GTX 660 Ti uses the same GK104 chip as the GeForce GTX 670. It also has its memory interface cut back from 256 to 192 bits. One of its four render back-end clusters is also disabled. Otherwise they are the same. You will get better performance from a 670 but like you said it does cost 40 bucks more. There will always be one that just a bit faster and a bit more expensive. I would go with the 670 if I were choosing for myself.
If you plan on using multiple monitors or anything over 1080 go with the 670, however if your using a single monitor the 660ti will be fine. I have the MSI 660ti PE and it works great for all my games, BF3, Skyrim with a ton of graphic mods, sleeping dogs.
If you want to get the 660ti, get the 2gb, not the 3gb (unless you actually need 3gb vram). Getting that much vram is usually meant for people running 3 monitors in surround mode. The 670 actually has a noticeable performance increase over the 660ti. If performance is your first priority, then get the 670. If you wanna save some money, the 660ti will be able to near max on all games on a 1920x1080.

That makes the Asus 7% faster outta the box than the EVGA SC, 6C cooler and almost 1/4 as loud under load (every 3 dBA is a doubling of sound level). The FTW is slightly faster than the SC, leaving the Asus model w/ just a 5% performance advantage
