So, i recently bought myself a new MSI Raedon 290 Gaming 4GB GDDR5 and have experienced a lot of issues recently. In games like Wow, Lol, Csgo the game runs smooth at high FPS for maybe 5 minutes, then it starts to shutter and the FPS drops to >20 every two or three seconds.
At first i thought it was a driver issue, so i reinstalled my drivers. Unfortunatly this did not have any effect. My specs are as followed:

PSU: Corsair CX750M
GPU: ROG R9 290x Matrix Platinum
Mobo: Msi B75MA-P45
CPU: Intell i7 3770
RAM : 16 Gb, i think they are Balistix. DDR3

What i've tryed so far is :
Repositioned the GPU
Updated BIOS
Reinstalled GPU drivers
Checked for loose powercables

 
Solution
Try going to Amd catalyst control center and set your power limit to 90 or max my brother had the same problem and this fixed his
I don't have the temps as of now, but i'll get then im a sec, and my previous Gpu was the Nvidia EVGA Geforce 560Ti. I did install my drivers on a fresh OS, so there is no trace of the old Nvidia drivers
