hmmmmm alrighty.
I just find myself doing a few things at the same time, such as extracting files from a large .rar archive, while attempting to chat (using a sluggh web-based java program) and do very light photochopping at the same time.
I remember when I had my dual 366's @ 550 on a BP6 how robust and capable that rig was, hence why I wanted to reproduce that.
Maybe just getting a Mobile XP2500 and clocking it to 2.3ghz, 1gb of ram and increased HD speed will let me do that?
