The 960T & mobo does make a difference, so does the power supply. I have a 890FX (125 watts TDP) and a 790GX (DDR2). I get Higher clocks out of the 790GX because it was made for overclocking a 140 watt BE. The Antec neo 550 is better than a Visiontek 1000. Because the NEO delivers more watts to mobo & CPU. The Visiontek will run more vid cards. IT is more suitable for stock clock i5 or i7, not good for OCing a 6 core thuban, barely has enough for a 960T OC to 4.0 Ghz. There is not much real world difference between 8 Gb 1066 DDR2 & 8Gb 1600 DDR3. 3.6Ghz is not bad and is within what I suspect a 95 watt mobo TDP. My MSI core controll on the 890 and HWpro on the 790 both say 3.9 Ghz and a 960T is 114 to 130 watts.
