On my desk machine at work (the only place I use a screensaver) I use the blank screensaver (blank.scr) for windows...not sure if it still comes with win98, but its on win95 I'm pretty sure. It doesn't suck enough cycles to worry about.
I like taskinfo2K as well; it only uses 0.08% of cpu when running, as opposed to ATM, which uses about 68.0% when running.
TO THE REAPER: Welcome to TA! Every crunch helps! Nice overclock, too...one of my crunchers is a BX6-r2 (also have an original BX6 crunching) and they are great boards still, even after a few years.
