Looking at buying the new Core i7 based Mac Pro... thinking the 4 core with 8 GB Ram... I'm a programmer, and my current (older) windows box has 2 video cards so I can drive my 3 monitors which is VERY nice when programming. I also game, so I want the better Radeon 4870 graphics card... My question is, is it possible to put a 2nd 4870 into the Mac Pro? I know you can't order it configged that way, but you can order the 2nd card (4-5 week wait). I tried asking both the Apple online sales chat support, and the applecare tech support people and neither really had an answer (in fact, some of the stuff they told me was absolutely ludacris... Like "If you order it with the Raid card and the fiber channel card, then you can use 2 radeons" (which is impossible because there's only 4 slots and you'd need 6 to run all that!) On the apple forums there's a thread where somebody said it's not possible to run 2 4870's because the bus can only provide 300W and 2 4870's require more than that. Anyone know what the deal is here? Could I possibly just get a 2600XT as the 2nd card instead? Will that work? Honestly, under Windows, I only really need the 1 monitor (24" Dell 2405FPW) but under OSX, I want to have my desktop stretched across all 3.
