I have no idea. The 8500 is completely new with a 450 Mhz RAMDAC I think and offers very nice dual monitor support as well as unserpassed performance. I can't imagine I would notice any diference in quality between a Matrox and a regular Radeon escept at maybee the highest resolytions. But I can't say anything about the 8500 though as I can only assume it is better then the first Radeon. The 8500 is also much more expensive. So if you need the best quality at high res (1800x1600) or higher go with the Matrox as it is far less expensive but if you don't need such high res then go with the original Radeon DDR as it has great 2D quality plus the aditional performance, quality, 3D, and the best DVD playbeack and features of the Radeon.
