ATI has two great cards on their hands. 4850 for mid range, and 4870 for the high end. Then when the 4870X2 comes and stomps the GTX 280 for cheaper. Props to AMD/ATI. Back to the days of the X800 and X850 when ATI was really on their game.

Edit I may have to grab an 4870. Sell both my GTS and GT to get the 4870.
