I just got a Sapphire X2900 XT and I'm very happy with it. I have briefly tried COH w/DX10 and it doesn't look all that impressive. However I did run the Call of Juarez DX10 benchmark and I get a higher AVG fps than most people running 8800GTS 640mb. Since the card has been out for only a few weeks, I'm sure ATI's next drivers will help out performance quite a bit.
