I just got that card today. I have an Abit KA7, Athlon 750. Latest Via drivers, bios, DX8, Win Me. I couldn't run stable 'til I installed the Beta drivers and set the VxD to normal (via agp driver setteing).
So it is working but I have nothing to compare to. Plus my system may be a bit diferent from yours.
Oh by the way if there is a diff in performance it's ussually pretty small. If it works don't screw with it. But if you do I hope it goes back to normal if it don't work.
