I'm rehabbing a performance 450 sn0014460719 to donate. This computer has a p3, 450/100 slot 1 cpu. does anyone know if a cpu upgrade is possible, and if so how fast will this machine support? 600-700 would be great. 1ghz is too pricey. \nThanks in advance. Rick.\nthe motherboard is a jabil bx part number 4000502. gateway support gives no info on cpu upgrades. I can buy a cpu in the 600-700 mhz range for about twenty bucks.\nGateway support link [URL]http://support.gateway.com/s/MOTHERBD/INTEL/m00264/M0026428.shtml[/URL] Is that 450 p3 all you can do with this machine ?
