Think the overclock above me has been rated before, but I'll rate it anyway.
My rating will probably be slightly wrong because it's been a long time since I've ever had a Q6600 (I know yours is a Q9300) and I've never overclocked one. My rating, 8/10 I guess.
Here's my overclock, sadly wanted 5.0GHz but I don't think I can achieve that without more vcore, and I set myself the limit of 1.45v.
Temperature on Prime95 blend reaches around 75C at most on the hottest core. Average is about 70C. Normal use up to about 60C if under quite a bit of load. Idle at about 23C. Water cooling, meh? Noctua NH-D14 does it for me, no water to worry about and a nice high overclock with fairly reasonable temperatures
