CrossFire came out with a huge overall scaling lead over SLI, and removing the one title that didn’t reflect that average would have made the lead even bigger. Superior scaling allowed two mid-priced Radeon HD 6950s to approximate the performance of two higher-cost GeForce GTX 570s, while three HD 6950s took the performance win over three GTX 570s.
Nvidia used there GTX 560 to destroy the hd6870 competition, and it did. The GTX 560 Ti is much, MUCH better than the hd6870.
if you're gonna do crossfire then i would use the hd 6870 but if you're just gonna do 1 GPU then i would use the 560ti. also since the 560 is already 230 after rebates at newegg might as well get an ASUS OC 560 to 900mhz for like 240 after rebates http://www.newegg.com/Product/Prod [...] 6814121425
or you can get a GIGABYTE 560ti oc to 1000mhx for like 270.
