Well, I've come to the conclusion that a socket 939 single core CPU is utter crap when it comes to 3D benching (with Aquamark 3 at least).
The CPU is quite clearly holding back my GTX 260 video card. I've seen people with better systems running with a GTX 260 get better scores at stock speeds than I can get at my max overclock. It also seems that my GTX 260 is a dud though, because it can't get past 645MHz on the GPU core clock. It absolutely will not even try to go beyond that, and if I try to set say 650MHz it will revert back to stock settings even when I'm just at the desktop and not running any 3D applications. Either it's a dud or it just doesn't like running overclocked in this system.
I've got the video card up to 645MHz core, 1100MHz memory, and 1500MHz on the shaders. I haven't really put much of an effort into it though, given that I know very little about GPU overclocking and don't know what it's limits are as far as how far I can go without breaking something I've been a bit on the cautious side with my overclocking fro this one.
Anyway, I've got a submission in for 112,584. Which isn't great, but it was the best I've been able to muster with the hardware I have on hand. Besides, I've been waiting on someone else to submit something, but no one has. So, at least we're closer to having the required number of submissions. Actually, a week or two ago there was another submission (I remember seeing four of them), but it has apparently been disqualified for some reason.
