i've got a celeron366 system at home that desperately needs a ram upgrade because it's 128MB aren't pulling for it anymore- ftp, seti, RC5 are always running
and when i used the computer at least 15 tasks are running at the same time.
granted, a processor upgrade would help as well, but when i had 256MB ram she ran just fine.
once i can get 128MB stick for $50 shipped, i'll jump on the ram bandwagon.
