I sold my PowerMac locally on Craigslist and pulled the load of RAM and a video card that I had in it to sell separately.
1) 3 x 512MB PC100 2-2-2 timing (Kensington Brand) - $37 each or $100 for all
2) 1 x 512MB PC133 SpecTek CL3A - $37
3) GeForceFX 5200 128MB - $40
This is a PC video card that I flashed quite a while ago and worked perfectly with my PowerMac, even running dual VGA. It has VGA, DVI, and S-Video output, though I've only ever tested the VGA and DVI (and the DVI was with a DVI-VGA adapter since I don't have a VGA monitor). Supports Quartz Extreme and Core Video.
