Now I'm under the impression that only the video card and cpu can be O/C'd. I' am planning on getting a 2nd gtx 670 ftw in 6-9 months. Is there a safe O/C level i can do with out getting a W/C? This is my system, and it will if needed i will max out the fans for the case, im just not comfortable with liquid being in my brand new system. Thanks for your help.
Ivy bridge overclocking is just like sandy bridge overclocking, there is a guide sticky at the top of the overclocking forum, start there and come back when you have specific questions. If you need more guides just use google, it is always a good idea to read several guides to make sure that all the info is matching up and makes sense to you.
I used this for my video card(same as yours.) my overclock didnt get that high. I see some got a 200 mhz gpu overclock. i could only get 115 mhz overclock. just one of those, luck of the draw scenarios!
