Radeon HD 7950 Review
Radeon HD 7950 is a high-end GPU based on the 28nm GCN architecture.
It's based on the Tahiti Pro Core and therefore offers 1792 Shader Processing Units, 112 TMUs and 32 ROPs on a 256-bit interface of fast GDDR5. The central unit is clocked at 800MHz while the memory clock operates at 1375MHZ.
Compared to Radeon HD 7970, its performance is much lower and behind NVIDIA's high-end GeForce GTX 660 Ti, despite being a direct competitor to GeForce GTX 670.
Radeon HD 7950 was later modified via a BIOS update and released as Radeon HD 7950 Boost Edition.
This GPU needs to be paired with a considerably strong CPU such as 3570K or any other CPU that offers similar performance. Upgrading this GPU to anything lower than a dual-graphics solution (such as GeForce GTX 690) is useless and not really worth it. Crossfiring it might be a good option, as well.

would suggest you get a 600Watt 80% efficient, if possible.

First of all, that is not just a 10% overclock, please update that figure to a higher %. Secondly The question is unclear. "How much the CPU strenght" If you mean to ask if your CPU is strong enough to handle the overclock, then yes, it is. But otherwise I don't know what you are asking.

not 10% ? so how much? i think it is beacuse i get in SF of BF3
83-85 FPS Average and the 7970 get 97 FPS
that's on ultra without AA
and with AA i get 63 FPS Average and 7970 get 69 FPS Average so i so close to the 7970 no? so i think this is OC of 10%
and maybe bigger

Thats not how you work it out. 1125-810= 315, 315/810=. 39%. That is quite high

Can't use stock fan to overclock, i used the antec h2o 620 for CPU, and have 3 system fans and the radiator fan, 2 intake and 2 exhaust. I have the Twin Frozr cooler on my GPU obviously.

It is MSI's standard version. Get mine, the twin frozr 3 version, similar price and runs quieter and cooler, This card can be overclocked to match a gtx 680. mine is at only 15 %. with afterburner you can get about 1100MHz which blows the stock 7970 out of the water
