for load temps, i would say anything over 75C is crossing the safe threshold. If u can, try to improve ur case airflow, or if u can spend around 30 bucks, u can get the zalman vf700 or any other reputable aftermarket gpu cooler (buy some artic silver 5, good stuff) and ur temperatures will be better than what u get with the stock cooler. all aftermarket coolers take up an extra slot tho, so if ur buying one, make sure u hv the space. Personally, my idle and load temps before were 52C and high 70's and after i got the zalman cooler, they were 44C and mid 50's.
