The PCI bus on any current motherboard doesn't run any higher than 33 mhz
anyway.  The 200, 166, 133, 100 mhz cpus use motherboard clockspeeds of 66 mhz,
with a 33 mhz pci bus speed.  The 180, 150, 120, and 90 mhz cpus use motherboard
clockspeeds of 60 mhz, with pci speeds of 30.  I believe the pentium 75 mhz uses
50 and 25 for the motherboard and pci clockspeeds, respectively.

In other words, this motherboard is NOT slowing anything down for the 200 mhz
chip.  You may get better performance when the Triton II comes out, or due to
other improvements that will be made to the motherboards between now and when
the 200 mhz pentiums hit the market, but nothing due to the bus speeds.
