I had a board almost exactly the size of yours running quite comfortably on a 2.6 MHz Celeron with 512MB RAM, using only the output of tuning-primer.sh as a guide. Your rig should easily handle your load using that tool (but your traffic levels are higher, so I'd suggest making sure that the mysql DB is running on a second drive, not the one that runs everything else, including swapfile -- especially during routine daily/weekly maintenance jobs, where disk thrashing was a bit of an issue)

tuning-primer.sh observes your mysql in actual use for 48 hours or longer, and then makes specific recommendations based on the actual performance of *your* site under *your* real world traffic.

These days, Mysqltuner.pl is also highly regarded, but I haven't gotten around to trying it. I keep meaning to. Both are free.

I don't have source links, but this thread has links and sample output.
