just so you know the B3 is only 105 watts while the G0 is 95 watts. the G0 will do better but saying that the B3 is 130 watts kinda sways too much judgement.
1. This is a two year old post. Check before posting.
2. The G0 stepping of the Q6600 was shown to outdo the B3 easily. It had a lower TDP, would OC to 3GHz on the stock voltage (or less like my case) and run cooler.
