PowerColor PCS+ HD5770 1GB GDDR5 (Vortex Edition) Pro Reviews

Nothing major has been changed with the PowerColor Radeon HD 5770 PCS+ Vortex in comparison to its other 5770s. The main differences are slightly better performance, a different fan setup and a free copy of the Call of Duty: Modern Warfare 2 game. The core has been overclocked slightly more as well, but the other cards could easily reach 900 MHz, though may not be warrantied to that level - something you get from a factory-overclocked card. The core was overclocked nearly 6% over reference 5770 speeds, and only 2% on the memory side. Without effort, 970 MHz core and 1360 MHz memory was easy to attain using only ATI Overdrive setting clock rates and fan speed. The gains equate to 8% more speed on the core from factory clocks and 11% more on the memory - not bad at all. Temperatures peaked in the high seventies, but often were in the sixties, especially with direct fan control.
