I had a lot of problems with the 4.15, but the 4.17 seems to be very stable. I definatly recomend it, it increased my video speed a lot, even though there is no gart driver for 2k/XP.
Just wondering, does anyone get more that 1x agp in 2k/XP with a via chipset? I have to use pstrip to get mine to 2X, the via inf driver for 2k/XP doesn't make mine 2X.
