Safe limits to overclocking?
I'm new to overclocking. I got my computer in November during the holiday sale on newegg.
Since then I've purchased Skryim. My graphics card is an AMD 6670. When playing on the default settings Skyrim detects for my computer (high), I get a lot of lag, especially in first person, which almost causes it to be unplayable. I want to overclock enough to play on High settings without lag. Or maybe High settings with some manual adjustments. I'm using AMD Overdrive in the control center. I have some questions.
What is a safe temperature to be at while playing?
What is "high performance gpu clock settings"?
What is "high performance memory clock settings"?
And how high should/can I go before risking damage to my card?
