Diamond Radeon HD5770 XOC

The HD 5770 has an almost perfect price to performance ratio. For app. US $160, you get a card with high FPS results in most modern games and DirectX11 support, Eyefinity and Stream. This graphics card comes with Colin McRae's Dirt 2.

The XOC, eXtreme OverClocked, version of this model has a GPU core @930MHz and the memory is clocked @1300MHz, which is an 9.4% increase for the core and 8.3% increase for the memory, when compared to the reference card.

Conclusion:

This grahics card has allready been factory overclocked, which resulted in app. 5% of overclocking headroom, this card performed better than the other mid-range and entry level products, including other HD5770 cards. You'll get great performance, at at a fair price, the cooler could have been better though. This is one of the fastest 5770 cards available.

With the AMD GPU Tool the results were 975MHz on the core and 1450MHz for the memory, as you can see there's Low additional overclocking headroom. These results were stress tested with Furmark. The GPU temperature was app. 80 degrees Celsius mark. The Fan is loud when over 60% rotation speed.
