Issue with gaming, low performance

[Payne99]

Hello, currently having an problem when trying to play multiple games on a friends PC. Mainly WoW is my biggest concern right now as I stutter and have fps lag issues. WoW crashes instantly as well when I activate AMD Overdrive. On another PC this graphics card ran perfectly smooth when playing WoW.

The build for PC makeup is:
-965 Black Edition 3.4 Quad Core
-MSI 870A G54
-630 Green Edition Coninuous
-Radeon 5970 black edition
-GPU Overdrive causes WoW to crash instantly
-8GB Ram

I can post his dxdiag if needed. Hope this helps and thanks for taking a minute!

So you have problems while using overdrive? Why use it?

Your power supply cannot meet the demand the card is drawing stock, let alone while overclocking.

Bone stock the 5970 takes 300w at maximum load, and the 965 140w or 125w depending on what version stock. That is almost 100% load. When you overclock the 5970 at all that 300w number increases greatly causing you to go over the efficiency area on a low end PSU.
So in other words, WoW is crashing because the 12v is dropping too low to the video card.
