I have a Dimension 9100 ( yeah i know it's old) and i am looking to upgrade my processor. Currently i have P4 630 and its running a bit sluggish so i have been doing some research. It looks to me like people are using Pentium D 950's and are having success. I found one for about $40 but i am hesitant to purchasing. The Dell documentation on this computer says the max cache is 2M ( http://support.dell.com/support/edocs/systems/dim9100/en/SM/specs.htm ) though people are getting this 4M chip to work. Is the max for the mobo 2M cache per core? would this processor work?
