PowerColor HD 5770 PCS++ 1024M
 

PowerColor's HD 5770 PCS++ could be described as an evolutionary step from the HD 5770 PCS+, targeted at overclockers. It is the first HD 5770 that comes with a Volterra voltage regulator which allows software voltage control. This enables tweakers to get higher overclocks out of their card without complicated modding http://www.techpowerup.com/reviews/P..._PCS_Plus_Plus
