I have a compaq presario and that is in serious need of a new processer. The one I currently have is a cyrix M II-366 at 250mhz. I origenally had plans to overclock it but I feel it would be best to leave it be and buy a new processer. what I wanted to know is would I have to buy a new motherboard inorder to upgrade it to 1gig? By the way, you would'nt happen to know why it says 366 and runs at 250. All your help is greatly appreciated.
