Thanks for the info, I picked a GFX 560 TI up today.
My FPS are better, not outstanding though. In Rift I get about 50 FPS with settings on medium in an non populated area.
My Specs are
AMD Phenom II X2 550
8.00 GB Dual-Channel DDR3 @ 669MHz
1024MB GeForce GTX 560 Ti
ASUSTeK Computer INC. M4A785TD-V EVO
Should I be getting better FPS?
