IE no slot-1 processors, nor anything else that is not pin-for-pin compatible with the P6... and most AMD/other processors have multiprocessing shortcomings that also would make it not work. The Motherboard can support processor clock speeds beyond 450mhz, but whether there will ever be a "faster pro" is anybody's guess... A faster processor clock speed would help. This machine has a pretty good memory architecture, using 4-way interleaving to read 32 bytes in one cycle, as opposed to the normal pentium 8 bytes / cycle... and this is needed to keep 4 processors busy, of course...
