Well here's the data I took: GPU Overclocking Experiment.txt
As you can see, I got pretty good results. That's probably as far as I'm going to go though. After 700, I began increasing the Core in intervals of 5 while running FurMark to see how high I could go before it crashed. (My temps were always fine) I got to 720. When I clicked apply with 725, the app froze and Vista told me it had to reset the Display Driver. Luckily I didn't have to reboot.
As for the memory, I haven't tried maxing it out yet, but I may amp it up to around 1280, since it seems to have a large affect on the overall performance.
What do you guys think?
As for me, I'm gonna go enjoy FSX overclocked!
