Hi i have ATI Radeon HD4350, i know its a low end card but that's what i could afford , so i have oc'd it using ATI catalyst tool, the GPU clock settings is 640Mhz and the memory clock settings is 540Mhz. The temperature is around 43c-45c at idle and around 55-57 at max load ( i used the ATI Tool). So on the long run will this oc damage my card?
