how much vcore do i need

[ahmedpegaz]

what would be the perfect vcore for a core 2 quad q9300 3.1 ghz oc

Well thats up to you to test out, usually if the stock for example for Q6600 is 1.325V you can undervolt it to 1.2V and keep it stable, now at 1.325V you can OC it to 3.0GHz without increasing voltage at all but later it need 1.45V or even 1.525V->(which i dont recommend in long run).

Its basicly push FSB till the PC doesnt boot, then lower for example 10-20 then test it with intel burn test for 10 passes, if it passes then you increase voltage from for example 1.2V to 1.25V and do the same scenario, its basicly trial and error, there is no specific voltage for specific overclock, since every chip differs from others because of the silicon lottery.

It's different for every CPU.
