My question is, would any version of the 660ti fit in this motherboard?

Yes it will work, as long as you have enough space in your chassis (especially length)
It will work. You have two PCIe x16 v2.0 Slots on that motherboard which is compatible with the GTX 660ti. Just make sure that you have enough space in your case. Most of them require 10.7 inches or less.
