Well, I made the upgrade and I'd say the bottleneck is now gone- my pc flies now.

The only thing I'd mention is that this mobo is apparently very picky about RAM. I ordered 1gig of Kingston (2x512MB) and it runs fine, but with my other PC3200 mixed in it only sees it as 166Mhz instead of 200(runs fine at 200Mhz in another machine and cpu-z IDs it as 3200). It has a list of preferred RAM in the manual and I'd recommend sticking to it... No matter, I'll just order in another gig of the Kingston.
