dude, i think that is a little too much lipstick for that pig. time to join the year 2002 before it is over and go to a DDR mobo. what is the point of OCing a SDRAM system when the memory will be your bottleneck for performance? your best bet is to get a nice refurb KT333 mobo with a 1600+ chip. get some decent PC2700 RAM too, and boost the FSB to 166 with the 1/5th divider.
but you see, you'll have to get a new mobo, video card, chip, and RAM. that's quite a bit a dough. your system is pretty good by itself--why don't you just save your cash and get a KT400 (should be called a KT333a) mobo, good DDR, and a 2400+ chip when they come out. i'll bet you hit FSB 166 with the chip and blow away your old system.
