Q6700 potential upgrade

[Bobsterman]

Hey there I came into building computers fairly late starting with skylake but have built more than a few using older parts aswell. I came across an old system that someone was throwing away which had a q6700 and 6gb of ram in the form of 3 2gb sticks. I got bored and decided to water cool it and got it stable at 3.7ghz. The main point of this was to ask if I was to update to a x5460 what performance could I gain potentially and also if voltage across the q6700 and x5460 is similar as to keep the q6700 stable at 3.7ghz I am at 1.5875V, it does not break 62C though even under load. Not scared to potentially break the computer but would be cool to get as much performance as possible for just a bit of fun.

I have an X5450, I had to pump about 1.45V through it to hit 4.0GHz, and then I ran out of motherboard FSB to go higher. You could try to get a QX9650 and shoot for around 4.5GHz using multiplier only. I was able to hit it with 1.6V pushing through it, but hit a thermal wall after that, even my custom loop couldn't keep it cool at 4.6.
