At a 66mhz bus speed you will NOT see much of a difference in
system performance between EDO and unbuffered synchronous SDRAM.
This may have changed recently but you can not mix them because
doing so requires 5.0 volt (signal level) tolerant memory chips which
weren't available earlier this year.
Do you HAVE to upgrade now or just planning ? I would wait until next
year when Intel releases a 100mhz bus. Aside from faster CPUs and
bus speeds, games will really benefit from 3D video cards that use AGP.
