Don't you need a WinPC to flash gpu cards?
No, but if you're flashing an AGP card you'd need to have a PCI video card in order to do the flashing on a Mac.
I thought you could do it w/OS 9?
I've mostly used OS X. I think you can even flash the venerable Radeon 7000 in a Mac now, although I've always used a PC under DOS, which was the "original" way to flash a Radeon 7000. There may be some OS 9 flash programs. The 2005 ATI flash program was "carbon" and will run in BOTH OS 9 & OS X.
If you flash a card and get artifacts in the display, this is a mismatch in the speed the ROM sets and the speed of the chips on your card. It can be tweaked by underclocking the card to match the chip speed. This isn't normally a problem, but it can occur, and some people think it means the card is bad, when it only requires a tiny tweak to make it work perfectly.
