First of all, like I said in my original reply, I am certainly not trying to talk you into the Q6600. The 45 nm certainly has its advantages. Heat, SSE4 instructions, (alledgedly) a better architecture, etc. However, I do not personally believe the Q9300 justifies the additional $100. Most ppl find a solid oc and run it all the time. I believe your board has software that will allow you to set oc'ing profiles that you can load at will to oc to different amounts. Most ppl would agree that software oc'ing does not generally work as well as making the changes in Bios, though.
