Thanks for the response. What would you GPU would you recommend if I updated my processor to an Intel Core i5-3570K Ivy Bridge 3.4GHz OC'd to 4.0GHz. I plan to buy this processor later. I was thinking of just doing SLI with the 560ti but I was also thinking of moving up to the 680 or 690.
Since you already have a GTX560 Ti, you could always SLI
However, just make sure your PSU has enough juice.
Though if you have the money to invest in a 680 or 690, I would highly recommend the GTX670 as it's the best bang for your buck at the $400 price range
