R9 290X throttling unless AMD Gaming Evolved is running?

This is a very weird issue and unlike any I have come across before. I have a reference 290x. Mind you, it is in a very well ventilated case and I have a custom fan speed curve in MSI Afterburner. This keeps the temperatures below 75C.

The problem is this: With AMD Gaming Evolved running in the background, the core is rock solid 1000mhz in every game... If I simply close the program and run a game, I see the core going haywire in the on screen display. It will stay at 850 for a while, then sit at 750, then jump to 925... huge difference...

Why is this? I feel the program is unnecessary and would otherwise delete it, but for some reason it is effecting performance. For now I guess I'll just leave it running, but I assume some others who do not monitor their core and realize this will have a tough time finding the culprit.

At first I thought it was throttling because of VRM temps, so I ordered a new heatsink that covers the GPU and includes a VRM heatsink... Now it's clearly just something to do with software. Guess I'll just use the new heatsink for a bit of overclocking.

Anyways, hopefully this explains what's going on thoroughly. Thanks for any help!

Download GPUz and UNinstall Gaming Evolved if you wish.
With CCC you should be able to find the problem, Using GPU z see what it reads your default clocks at and current clocks and what performance mode its in.

Also the 2nd tab shows sensors, please switch to it and take a picture of what the sensors are looking like, this will tell you if something really is throttling your GPU as it will show the increase in voltage, temp, gpu usage, and clocks.
