I thought that might be the best option. The dual fans/extra ram on the others were leading me to believe otherwise. But the extra cores on the Ti can't be beat I suppose. Thanks.
No way, just no way.
The value of GTX 660 ti isn't very good. http://www.techpowerup.com/reviews/Club_3D/HD_7870_jokerCard_Tahiti_LE/30.html
You should go for GTX 660, it's like 75% of the Price of the GTX 660 ti and it's only about 10% slower.
