I am putting together a 386 which will be used for graphics along with other things. My question is that does the cache make a significant difference and if so how much ? I have heard opposing views. i.e. the cache doesn't really make any difference and that it makes a big difference. Since 386 motherboards with cache are about $300 to $400 more expensive, I think it is better to use that towards a start on a good graphics coprocessor. Any views will be appreciated. Thanks

I use a Compaq 386/20e at work and built a 386 clone at home. The Compaq runs at ~20MHz with a cache and the homebrew at 25MHz without one. They both have 22ms Hard disks and 387 coprocessors. I cannot distinguish any difference in performance between the two machines even when running graphics-rich applications such as CAD programs and DTP programs. I would sink my $ in a FAST disk drive. In addition, some clone boards provide memory interleaving when all RAM banks are filled, providing (for me, anyway) an increase in performance from an equilavence of 25MHz to 31MHz. -- Jim Adams -- James F.
