I agree, if video is what you do. However, the faster bus on the IPC, and
the total lack of color if you are running it with the built in FB make
it about as effective for command line work. I have always preferred
busses running at chip speed, my favorite intel chip is still the
486DX/50, not to be confused with the DX/2. I'd really like to see AMD
come our with a 200Mhz K7 running on a 200Mhz bus, with 200Mhz memory
clocking. I bet it could give the 600/200/100 Mhz one a run for it's
money on bus intensive applications.
These new multi-pipeline chips running twice the speed of their L1 cache
and 6 times the speed of the PCI bus must spend an awful lot of time
twiddling their thumbs.
