Well I'm finally going to break down and setup SLI. I am still looking at these two for SLI:

GeForce GTX 560 (Fermi) GeForce GTX 560 Ti (Fermi)
Core Clock 810MHz 900 Mhz (v.s. 822 Mhz reference)
336 Processor Cores 384 Processor Cores
MemClock 4000MHz 4212 Mhz (v.s. 4000 Mhz reference)


Will I really notice a difference between 560 and 560ti running? Right now the most graphix intensive thing I will be doing is playing BF3. I've dropped all the other gfx stuff.

also will the PSU in my sig be enough for SLI and all my other parts?
