I want to run a program that is to much for my PC so obviously it needs updating... I currently have a PII Slot-1 Motherboard with 500Mhz (100Mhz) installed in my case and can't find the Intel PIII 700Mhz processor to upgrade it. (that is the largest it will support) How do I know what motherboard I can use to replace it to get more power to run my apps.
