Only tested a few games. I had the older 6037 drivers. I still had the "High Poly Bug"/texture issue. For SS:SE, 1024x768 using quality setting the cathedral demo gave me 48.1 fps on a 1800+ XP. With these I got 88.5 fps. Ran it a few times with each run almost the same. 3dmarks when up about 300 points. Did not see any change for good or bad in UT (running it in OpenGL) mode. Did not bench CS but it always seems to run smooth. So far I like em.
