Interestingly, I just saw on newegg a GTX 285 "for Mac". I read one review of someone who put it in their Mac Pro. I guess that means that there are drivers for a GTX 285 and it's fully supported? Also, what would the difference be between the different card manufacturers? I'd like to go with the Gigabyte but it only has one review on newegg (which may be a good thing, depends on how you look at it). lol also my machine just happens to be a mini-tower, so I'm wondering if this thing might burn up inside the case. Eh, it should be alright, if I install another fan I guess.

EDIT:
Alright I've done a crapload of research. So there is a GTX 285 for Mac, and it's drivers can be used with the hackintosh if I also use an injector, as near as I can tell. The other option I might explore is making my own Mac card by changing the EEPROM chip and flashing the card ROM. As far as I can tell though that actually isn't necessary since I'm dealing with PC hardware and a BIOS and all. Someone correct me if I'm wrong... :P
