clean ur drivers out. Use rc11 driver 8.921.2
I HAVE THERMALTAKE TR2 550 WATT..

Oh, and out of curiosity, can you run a test with task manager (or similar) to see what your CPU usage is while playing? If your CPU is pegged out, you may just be CPU limited. Although I would think this isnt the case, its worth a check.
That is 2x 12V rails: 17A and 16A, so that is 204W and 192W.
Although the 7950 should consume similar power to a 4890, it is possible the PSU isn't up to the task due to natural ageing degradation, especially if that CPU is working harder.
I would do a clean install of windows first - that would remove driver/OS corruption out of the way.
Then it can be either a bad GPU or a insufficient power supply. Generally bad GPUs either show artefacts/corruption and or simply crash under load.
What kind of temperatures are your CPU and GPU hitting during game sessions?
a new psu can solve the problem?
If it is the problem.
But before spending money, I would try all non spending money solutions.
Fresh Windows install, OC the CPU, making sure the pci-e connector isn't from the same rail that is feeding the CPU, take the card out and reseat it, etc.
Temperature of the card seems fine.
Would hate to tell you to buy a new PSU and that turns out to not be it.
True that, but the TR2 line from Thermaltake is not known as being a high quality, modern power supply by any stretch of the imagination. *
My 600 tr2 with dual 12v one being 32a and the second at 24a at one point and time powered up a 4ghz 1100t and a gtx570 with no fuss of any kind and while i had no plans of this exact model as i got it in a pinch, it held up very well.
I am sure for any modern gpu like a 7970 with a moderately oced 2500k it would be perfectly fine as both would consume less power then the 1100t@4ghz and the gtx570.
No plans for sli or crossfire or the ultimate gpu or cpu oc so it works.
While I think you are CPU bound (CPU at 90-95% is showing that), it still looks like you are having power supply issues.
Do you have access to another machine to test your card in, or test another power supply in yours?
Were you actually getting higher framerates with the 4890? You shouldn't be getting lower framerates unless maybe the CPU is throttling.
It could actually be CPU bound because the 7950 is a much more powerful card than the 4890.
However, you should definitely check CPU temps...if they are getting too hot your CPU will throttle down, causing it to run at a lower speed, and you may get the CPU usage at max because of that.
Report your LOAD CPU temps (use Prime95 to get a full load on the CPU) using Coretemp or the motherboard program.
