I unplugged an optical and HDD to see if the score would budge, but nothing happened... so while that's a (small) amount of evidence the PSU's enough, I'm not quite convinced it's not the PSU causing the problem. Because of that, I think I will be ordering a new PSU this weekend... I actually found an "inexpensive" PSU that was reviewed nicely: newegg's housebrand, "Rosewill" 750w, for $125 shipped. I may go with that, but I'm gonna go check the price on the PSU you're using. Gamestream = OCZ, correct?
Here's the one I am looking at:

Jonnyguru, among the major sites, has a good review of it.
EDIT: Popped timings down to 5-5-5 1T, and score went up to 15971... at least it's something :p... gonna look around at PSU's and then order one, I'm pretty convinced it's the PSU causing the problem.
