i bought the radeon 8500 64meg a few weeks ago to replace my matrox g400 max. it was a big upgrade for 3d, and it rocked, but i had to return it because it kepted pausing and crashing my system. i tried all types of tweaks, and driver revisions, and nothing solved the problem. so im back on my matrox g400 max for now. i never crash on my matrox card, but 3d is quality is lacking. fyi, im running an athlox xp @1.5hz, 768mb pc2100, epox 8hka+.
