8.3 Out of 10

Thanks to PowerColor's dual fan cooler the card is a lot quieter than the AMD reference design, and runs cooler too - pretty impressive!

The game graphics are top notch, even today, yet the game still runs well on most computers.

This power configuration is good for up to 225 W of power draw.

What People Are Saying Give it to me straight

Applications

Moving away from the European setting of previous Total War games, the game is now designed around principles of the brilliant Chinese general Sun Tzu and his book "The Art of War.

After the tremendous success of Far Cry, the German game studio Crytek released their latest shooter Crysis in 2007.
by techPowerUp! (Feb, 2012)
Due to the massive success of the first game, Blizzard chose to focus large aspects of the game on multiplayer combat through Battle.net.

Gaming

It is one of the first DirectX 11 games with support for new features like tesselation, which is why AMD heavily promoted it at the time of their DX 11 card launches.
by techPowerUp! (Feb, 2012)
Later installments of the Call of Duty Series use the same game engine, so this test is also representative of Call of Duty: Modern Warfare 3 performance.
by techPowerUp! (Feb, 2012)
StarCraft II features a similar number of units as the original game, some of them new.
by techPowerUp! (Feb, 2012)

Performance

Overall I would say the card is "quiet", making it a good choice for high-end gamers who want to enjoy their games without a lot of fan noise coming from the graphics card.
by techPowerUp! (Jan, 2012)
Sapphire's HD 7950 Flex uses a higher GPU clock than the AMD reference design, which will help gain some extra performance.
by techPowerUp! (Jul, 2012)
You may combine up to four HD 7950 and HD 7970 cards from any vendor in a multi-GPU CrossFire configuration for higher framerates or better image quality settings.
by techPowerUp! (Feb, 2012)

Overclocking

GPU overclocking works well, but the final overclock seems a bit below what we have seen on other HD 7950 cards (AMD ref: 1085 MHz, PowerColor PCS+: 1145 MHz).
by techPowerUp! (Feb, 2012)
Since the card uses the same CHL8228 voltage controller as the reference designs, overclocking with existing tools will be a breeze, and the card is officially supported by MSI Afterburner, too.
by techPowerUp! (Feb, 2012)
The greatly improved cooler and the overclock out of the box actually makes the choice a no brainer.
by techPowerUp! (Jan, 2012)

Cooling

We also tested the PowerColor HD 7950 PCS+ today which is a lot quieter and cooler, AMD should have chosen a better reference cooler.
by techPowerUp! (Jan, 2012)
PowerColor decided to scrap the AMD cooler and use their own dual fan design.
by techPowerUp! (Jan, 2012)
While it's not as quiet as other HD 7950 designs (PowerColor PCS+), it is still a huge improvement over the standard cooler.

Only 1995 dollars? Hot dog!
Go with these heavy power hungry GPU's if u have a 27" to 30" monitor or triple display setup because the 7950 has more headroom(2560*1440 n 2560*1600) to play above full HD 1080p maxxed out settings. u got a 22" monitor u can always go with a HD 7850 or 7870 graphic cards as they are more than enough for playing games at full HD with ultra settings.
