Sudden performance issue only when playing games

Hey people,

Two weeks ago I decided to install Diablo 3 to get ready the expansion. Right after the install I decided to run the game and noticed that the screen was choppy. It was as if I was playing with very poor FPS. I didn't think much of it and thought it might only be temporary, but it never went away. I decided to test out other games (Dota 2 and CS:GO) which were running fine on highest settings and now they too were experiencing the same exact issue.

Here are the troubleshooting steps I've already gone through:
-Scanned for virus/malware/spyware/etc and cleaned found problems
-Uninstalled video card drivers (with Display Driver Uninstaller via safe mode) and reinstalled latest drivers for my card
-Uninstalled Diablo 3 and tested other games
-Ran Windows Update to ensure latest patches/updates were installed
-Reformatted my computer and installed Windows 8.1 (was using Windows 7 before)
-Enabled high performance for Windows & in my video card control center
-Opened my case and reseated the RAM
-Tested my video card in a friends computer and it ran games fine for 2hrs+

Everything else on my computer runs fine (YouTube HD videos, DVD movies, all other programs that aren't games).

I built my computer last year and it was running fine up until two weeks ago. Here are my specs:

(I didn't overclock anything)

Motherboard: MSI 970A-G46
CPU: AMD 6-CORE FX-6300
PSU: CORSAIR 500W CX500 R
Video card: SAPPHIRE HD 7870 GHz Edition OC 2GB GDDR5
RAM: G.SKILL Sniper Series 8GB (2x4GB)

If anyone has any expertise or ideas as to where I could go next in terms of troubleshooting or solving my issue, I'd greatly appreciate it.

Thanks in advance!

Reset the BIOS by clearing the CMOS (remove the battery for 30 seconds or use the jumper)

Just tried this and still no resolution. I think it may be PSU related.

My friend who tested my video card is running a 750W PSU and mine is only 500W. I'm going to test this out when I can get an extra PSU with more wattage. Thanks for your input!

It won't be PSU related.

Alright then. Any other possible suggestions?

Re-apply thermal paste on the cpu? I'm willing to try anything.

I'd see if another GPU works in the PC.
