Hello everybody. Now that people starting to use PC 8800GTs in their new Mac Pros I was wondering if anybody already tried the ATI HD3870x2 card in their mac pro? I assume it will run in Bootcamp and thought I will give it a try ... I was not so happy with a PC 8800GT in the second PCI slot since the fan made a constant 100% speed noise in Mac OS X. Will the ATI card behave the same? For a short time Apole listed the HD3870 as option for the Mac Pro ... anybody knows something about the Bios / EFI? I heard that at least Crossfire could work in the new Mac Pro. Does it make sense to connect the HD3870x2 to the stock card HD2600XT in the Mac Pro??? Thanks for help and suggestions.
