Is it worth disabling hyperthreading in my i7 system to lower temps and gain a higher clock speed? Currently i'm running at 3.6 ghz on my 920 chip and I can't go higher without my temps reading over 75c in realtemp.

Disabling HT will allow an additional ~ 200 Mhz at the same Vcore with a decrease in temperatures of up to ~ 12c.
That's pretty significant, i'd do it. Keep in mind i do a lot of gaming, not as much multi-core intensive programs. But if you can drop up to 12c off your temps you can up the voltages a but more for some pretty good mhz gains.
Some benchmarks show that HT can actually hinder gaming performance. If you are almost exclusively gaming, you would be even more to your benefit to turn off HT and increase the overclock, or even leave it at its current speed to lower temps slightly. Either way you could increase gaming performance.
