How much could I reasonably ask for my current setup, I have a G0 Q6600 that can clock to 3.6* at least when I had 2 sticks of ram, it won't get much past 3.3 with all 4 slots though, a gigabyte GA-X48-DS5 and 2x 1gb Giel PC2-6400 ram and 2x 2gb Kingstone PC2-6400 ram?

*(max I ever got was 3.8ish but the power draw at that level is immense it uses almost 150w more at the wall for an extra 200mhz due to the large voltage increase needed to run past 3.6) although that is with a cheapo power meter that is wildly inconsistent now, I think it may be broken.
