I'm thinking of getting a GTX560, is there a big peformance gain between the GTX560 and the GTX560Ti?
I'm on a budget of about £700 and as I posted before, my rig :
AMD PHENOM II X4 965 (3.40GHz/8MB CACHE/AM3) - BLACK EDITION
ASUS? M5A87: AM3+ PLATFORM, DUAL DDR3,SATA 6.0GB/s, USB 3.0
8GB SAMSUNG DDR3 DUAL-DDR3 1333MHz (2 X 4GB)
1GB NVIDIA GEFORCE GTX 560 - DVI,HDMI,VGA - 3D Vision Ready
CORSAIR 650W ENTHUSIAST SERIES? TX650 V2-80 PLUS? BRONZE
Are there any cheaper GFX cards that will be equal or better to the GTX560?
I'll repost this as it didn't get answered twice before(just making sure it doesn't get lost)

If you're going to be playing at 1920x1080 then the 560Ti is the superior choice.
