I've been poking at this for awhile as well with no real performance improvement. That's why I'm hoping that someone has another Intel based machine with a Nvidia/ATI/or different series Intel chipset to test with so we can narrow things down.
I'll keep poking at this, but most of the knobs have been covered and being on a Dell box means I'm limited in tweaks and overclocking. For the current WUs, a 2600/3600 series GPU seems to be the best bet. As proteins get larger, the 3850 AGP may look better on this system. On AMD+Nforce3, things look pretty good with the 3850.
I offered it to you once and will again. If you want the P4 ASUS mobo etc its yours to test and keep. If it helps the cause and all those P4's out there wishing they could produce some nice #'s I'd gladly donate it.
