Asus' 2GB Radeon HD 5870 Matrix card pictured

I really want to see how Xfire 5770s compare to a single 5870 and GTX 480 with Tesselation.

On ATI cards, the tesselator function is fixed on all the HD 5000 cards, which is why the 5800s arent doing so good with it on. Two 5770s have more tesselation power than a single 5870, and the same as a 5970.

This is one strong reason why paying for anything more than a 5850 from the current ATI lineup is a total waste. Regardless of how high the max FPS are without tesselation, once tesselation is being used, the 5870 = a 5770 on the minimum FPS.
