I was stupid and didn't research it before I bought a 780i board to replace my dead 680i and realized my chipset waterblock isn't compatible. I am planning on OCing my e6600 to 3.3 like I had it...am I going to have to shell out the $$ for a new waterblock or will the stock heatsink work? It looks like a nice heatsink...and I have a fan directly on it. Any thoughts are appreciated.
