Sapphire Radeon HD 5770

"The Sapphire Radeon HD 5770 uses the RV850 GPU at 850Mhz and has 1GB GDDR5 memory running at 4800Mhz. The Sapphire Radeon HD 5770 has a 128Bit Memory Interface, 800 Pixel Shaders and DirectX 11."

"Sapphire Radeon HD 5770 gave an amazing performance against the Gainward Radeon HD 4870 and the result was very interesting. I was not expecting the Sapphire Radeon HD 5770 to outperform the Gainward Radeon HD 4870 so I was shocked to see how close the result was. Only twice the Gainward Radeon HD 4870 really outpaced the Sapphire Radeon HD 5770 and this was with the Fall Out 3 and Far Cry 2 results. In the end the performance difference between the Sapphire Radeon HD 5770 and Gainward Radeon HD 4870 was only 5% overall which is why I highly recommend Sapphire Radeon HD 5770!"
