Not sure about that card order, but if it works, then I suppose it's fine.
SBLive is not supported by anything other than a mixer, AFAIK there is no functional driver as an AHI device, but maybe you just want it as a sound mixer or maybe it's just there for bus termination. There is in-theory a driver in AHI v6.7 for OpenPCI but I don't know anyone that has gotten it working, maybe Trixster in his AA3000+ on Prometheus?

That benchmark result is not far off for a Voodoo at 800x600. There is a known issue that FPS drops off a cliff higher than 640x480, which should give you something like 50FPS.
Thanks @grelbfarlk, really appreciate the feedback.

The reason I set VoodooInt to No, is because if I Set it to yes my WHDload games do not start I just get a black screen I'm not sure if this is a bug with the Ratte Auto Switch SwitchControl (This Also happens on my 1200 Sonnet Build)

I will Adjust the VoodooMem and see how it performs

Now I'm a little confused by the SBLive, I thought, if it wasn't compatibly I wouldn't get sound in my Games when I select AHI? but I think I have a spare SB128 somewhere

I'll try Blitzquake at 640x480 see if I can get close to 50Fps
