well so far i have no complaints at all with the drivers, im using 2.3's, and they perform quite a bit better than 5.3's from ATI in 3D Mark 03 and 05 on my 9600XT, like 300-500 points in 03 and 15-30 points in 05

no bugs that ive noticed yet. the only thing i did notice, with the drivers is that they didnt like it when i overclocked the card at all, i left mem at stock 650 and core i went to 526MHz like the ATI overdrive and i was getting quite a few artifacts. with the 5.3's i could put mem to 670 and core to 560 and not get any, dont know if its something with the drivers or not.
love them

keep up the great work
