K8V-MX drivers ?

Upgraded my TX97-E (still perfect) to this piece of apparent
sh*&^&*t.
Sound does not work with most of my games, video gives me
blank windows if power down happens.
Diablo 2 is slower than with an old duron board I had (video
issue ?). Heroes of Might and Magic 4 ditto.
Quake 3 works fine ? Is that a lead ?
Have latest ASUS drivers and bios. Sempron 2600 cpu.
Win98SE
Any ideas ?

PS ... is my voodoo 3 pci 16MB inherently faster than the
onboard SIS chipset ?
