Assuming the bus is standard (PCI/AGP/PCIe)
Does a MAC edition Radeon/GeForce work on normal PC's? Or is there something in the firmware of the video card that may prevent it?
It's been a while since I've read about it, but I'm pretty sure you need to flash the firmware to get it working.
Generally it won't work, at least not in Windows or DOS, since those depend on the card's firmware to set it up initially. On a Mac-edition card, that firmware is OpenFirmware fcode or PowerPC machine code, while on a PC-edition card, that's x86 machine code. So, the Mac-edition card's firmware will, at best, not run on a PC. (It may *try* to and freeze the machine at boot, too)
Under Linux and BSD, some Mac edition cards can be used as secondary graphics cards, while some can't - YMMV, and you'll almost certainly have to screw around with it. Anything that tries to touch the firmware/BIOS will not work right while poking the chip directly will. I personally wouldn't bother, and I'd reflash the firmware if you can.
The same thing also applies to PCI cards designed for HP PA-RISC, Itanium, SPARC and Alpha machines.

Alas, I'm down to emulation.
Sometimes, for instance my Mac Edition HD4870 works fine in PC's, in general the AGP versions don't but the PCI express versions do.
Most of the PCIe ones were designed for AMD64 Macs, though, weren't they? If so, they'll have EFI firmware, which should work on a PC with EFI.

Yes they where all efi ones work on pc

The PCI-express bus was never used on PowerPC Macs, only on Intel Macs.

Your point, he never specified what type of mac, and just an FYI the Intel MAC's still have a diffrent UEFI boot code, its just that Nvidia and AMD ship their cards as cross compataible.

The Power Mac G5 had PCIe expansion slots, which is why I asked. (There are also other non-AMD64 machines with PCIe, like the newer IBM POWER machines, HP Itaniums, Sun SPARC servers and the Ultra 25/45 workstations, but the cards made for these aren't anything you're liable to trip over in normal use.)

*checks*
Oh, it's only the multi-core systems that have them...didn't know that. 😊
