Not quite true. Yes you can "hack" a PC gfx card to run on a Mac. The primary problem is the card's firmware. Mac cards require two set's of firmware, 1 for mac and 1 for PC (PC is needed for bootcamp). So enterprising users dump Mac card ROMs from official cards and then flash a PC card with it. Sometimes this requires replacing the flash chip on the card as well (as the combined firmware is obviously larger than normal). Unfortunately there is more to it than just flashing in straight up Mac firmware in a lot of cases as can be seen by the numerous threads on MacRumors to do with flashing various models with varrying levels of success.eman7613 wrote: Its actually ATI & Nvidia playing games, google for hacking PC gpus to run on macs, usually it is just re soldering certain points - otherwise they are the exact same.
Similar issues are faced by those building so called "Hackintoshes" it's definately not all plain sailing. The conclusion from my researching the subject prior to making my purchase was that hackintoshes are generally less hassle than the average linux system but still a hassle, especially around OS update time.
Here's an example thread on flashing PC 4870's:
Me, I would much rather pay a "premium" for a Mac Edition card and get something that works than stuff around trying to get some cheaper PC card to work...time is a commodity in short supply after all.
10 years ago I would have been all for "having a good ol' hack". These days I'm much more interested in getting things done than stuffing around with hardware.
