Choppiness after Overclocking?

My current system:

AMD Phenom X4 750K
600 W Thermaltake PSU
HD 5850 Sapphire GPU
MSI A78M-E45 Mobo
HP 2311x Monitor
9 GB of RAM

I just recently upgraded my old GTS 250 with a cheap HD5850. I decided to overclock the HD after installing in order to get more juice from the card.

I used MSI Afterburner, HEAVEN and GPU-Z as I overclocked. Like I read in numerous guides, I uped the core clock by 10 every time and benchmarked it to test for artifacts, glitches, etc. Nothing presented itself at all. The default core clock is 765. After about 800, I noticed no FPS increase whatsoever but it still performed fine.

Figuring I had hit a bottleneck of some sort, I went to overclock my CPU. Using AMD's OverDrive, I used the Auto Clock (Worst mistake ever) and waited for it to work.

Now, when benchmarking through Heaven, the FPS is very low but the "game" itself is going through everything quickly. Its like on turbo speed and choppiness is everywhere.

Oddly enough, videos still play fine on the computer. Im about to go check an actual game to see if anything is odd there. What could be going wrong?

well one of your problems (which you seem to recognize) was using the auto overclock feature on your cpu... i know of all of the crazy crap that will do to your system. For one it LOVES down-clocking your ram and blowing voltages through the roof for no apparent reason.

For example, my cpu runs and passes stress tests (pick one, it will pass it) on stock vcore and 4.5ghz... my ram is ddr3 1600 9-9-9-27 ram... out of curiosity i used the autotune feature... when it was done the system was so unstable it barely booted. It had set my ram to 1333 speed, changed the timings to 10-11-11-40, boosted the cpu frequecy to 224, the multiplier to 18.5, for a clock speed of 4.1 and change... it also pumped the vcore up to 1.45 and the cpu/nb voltage to 1.3...

the system was overvolted, so of course it barely worked... was way too unstable for words... i couldn't call that an overclock since it wouldn't have passed a stability test (heck it crashed 2 times durring boot)... simply terrible utility.

BTW: my CPU is 100% stable with 1.425V vcore at 4.8ghz... there was no reason for that program to blow the voltage through the roof for a non-existent overclock.

Just tried Civ 5 and the video is rather choppy. Still playable, but alot choppier. The loading time also seems greatly affected.

I restarted the computer just to see if maybe something wasnt right but that has done nothing for me. I have reset everything back to default but still, the choppiness persists.

Looks like during a game, I am seeing %20-30 CPU Usage. I would like to say that before trying to overclock, games ran for the most part smoothly.
CPU Cooler is stock. GPU Temp is 39 during no usage and about 48 during usage.

Okay. I did nothing different. But now, I benchmarked Heaven again and its fine. Infact, its getting higher FPS then it EVER has. What is going on? Ill have to look at my CPU Temp in a sec.
