I'm sorry, for not reading through every forum topic, flame me if you choose I'm kind of confused on the process of flashing a PC 5870 card into a Mac compatible one. I've skimmed through "The Golden Guide to Flashing Graphic Cards" and read up on the Zeus Flashing tool, but it seems it confused me more then I expected. I'm running a MacPro 3,1 8 Core with a NVIDIA GeForce 8800 GT. To my understanding, if I throw in a PC 5870 card it won't be recognized. How am I supposed to run Zeus then? I don't think I can fit both cards in at the same time. The power cables in my MacPro won't function with PC power cables so i need to modify them? Roms I look for in netkas? Is there a list of preferred 5870 models to choose from? ones that my have a lower cost or might have less compatibility issues? Thanks in advance!
