I think you'll find that latter bioses mostly sorted out the memory bandwidth performance problems ,I recently swapped out a dead BX board for a Soyo 7VCA (694x chipset).With the mem clock set to FSB clock (100/100MHz),bios soptions set to Turbo,4 way interleave & CAS2 the VIA board nearly matched the BX's board score in Sisoft Sandra with the same processor.Also running SETI(see my sig) which is very sensitive to memory bandwidth AND latency the times taken to complete Work Units were very similar too.
Here's the scores
Cel 366@ 550 ,Soyo 6BA+III BX chipset(not the board that died but it did have the same cpu)
RAM @ 100MHz,CAS2
ALU 314 Mb/s (about 10% faster than VIA chipset)
FPU 354 Mb/s (about 7% faster than VIA chipset)
Cel 366@550 ,Soyo 7VCA VIA chipset,694
RAM @ 100MHz,CAS2,Turbo,4 way interleave
ALU 284 Mb/s
FPU 330 Mb/s
As you can see the BX is only a tiny but better
