Hey guys... I am thinking about upgrading my GFX from my current 260, but I can't decide between a 560 Ti, 6950, or 7850. I am looking to play games like Crysis, Skyrim, and BF3 at a smooth 50-60 FPS on max settings. The Ti is the cheapest, plus I've read that it can be OC'd to about the same performance as the 7850, but I'm not too sure if I should still go with it. I don't want to fry any of my parts by overclocking, but if it isn't too much of a risk, I'd be willing to do it. What would you guys recommend? My specs are in my signature. Thanks!
