I used to have a Mystique G200, installed in a board run by my AMD K6-2 400MHz chip. Now I know that the Millenium is a bit better, but it's just a by a little bit. All Playstation games I've tried are near impossible to play, getting somewhere about 4-6 frames per second (yes, so slow that you can count them), and any amount of tweeking you do will not change this. But after I upgraded my Mystique G200 to a GeForce 2GTS, everything runs super smooth, as if I'm playing it on a real Playstation. There's not much you can do with a Millenium nowadays.
