Well im soon to have a cooler installed that would bring it down to maybe 40-50ish C. So once its installed should it be pretty safe to OC it?
Yea sure.. I will be honest and say the cooler was a waste of money. You aren't ever going to see good frame rates in Crysis with that card. It is just not going to happen.
Save and invest in something like an 8800 GT, 9600 GT (out soon), or HD3850.
