Overclock

I just overclocked my computer!
I first did +9% GPU/+25% VRAM. (+91/+174) (+in addition to +6% factory overclock) (stable)
I then did +25% RAM. (+266, It's only running at 1333). I didn't have to change timings any.
At this point, I was getting an average of 0.1% better FPS in games.
I then did +25% CPU BCLK -25% RAM (+667 MHZ/+266) RAM is still running 1333 due to BCLK change.
PCIe, SATA, USB, etc are on their own clock which I won't change.
I am now getting about 80% FPS improvement in games. 25% CPU boost translates to 80% FPS boost. Doesn't make much sense to me. Will run Prime95+Furmark all night.

Temps are a bit worrying for the CPU though at 96-97C, though I doubt anything but Prime95 will ever reach those temps. Also, the fans seem to be keeping it from getting any hotter.

Specs are in my sig

80% fps improvement in games? On more than one?
Getting 25% improvement would be shocking. 80% implies far more changes that can be expected. I hope the temperatures are survivable (I really can't tell anymore). About the only thing that I can think of that would cause such a thing (80%) would be some sort of banging into vsync issue.

Is there anyway to measure the ms between frames? The only thing I can think of is if they are fixed multiples of each other. But LCDs really shouldn't work that way (of course since g-sync and free-sync apparently help, they really don't work in the obvious ways).
