Prices on this card has here dropped below the Diamond Viper card
which is about half of the old #9 card.

I think that selling a VLB for a graphics accelerator card is like 
selling orange coloured golfballs for playing in the snow. 
VLB may be useful for a non accelerator card and for disc controllers, 
but not for graphics accelerators. The small traffic on the bus to the 
card just does not justify it.

I also wonder (forgive my ignorance but) how do I interpret the figures 
your benchmark produces? what is 'waits' ? Waitstates??? What is the 
source when the header says ->s or ->v and the target when it says s-> 
and v-> ?
