Now that ATI seems to be happy to spit out Mac/PC variants of the 3870, what do you think the odds are that we'll see a dual 4870 offered for we few, we happy few with the Mac Pro?? ATI seems to be on a roll lately, and is most definitely engaged in and winning a price war with nVidia. Obviously the 3870 offering is a stab at the nVidia Mac desktop marketshare. I would LOVE to have a dual 4870 for my Mac Pro. NATIVE Crossfire in Windows, on one card. Imagine the OpenGL performance on the Mac side as well!!! And what if Snow Leopard does capitalize on the spare GPU cycles to increase system-wide performance? Whoa.
