"In fact, manufacturers that make identical ISA and local bus adapters
have priced their local bus versions the same as their ISA products. Why?
Because they aren't any faster. The bottleneck is not in the bus — it's in
the CPU on one side and the graphics coprocessor on the other. Neither can
move the data faster then the ISA bus can move it"
If you know anyone with a subscription to InfoWorld, or if your library
has it, I suggest you check this out. Gibson is a master at presenting this
tech stuff in a clear, readable, and understandable manner and his logic is
irrefutable.

P.S. He _does_ mention one instance where local bus did show a performance
improvement and that is in "nonmainstream applications involving
nothing but colorful static image movement to the screen." That sounds
a lot like playing a flic file so maybe local bus is useful in this one
area.
