my q9450 at 3.4 folds better then my PII at 3.7 by 200-400 ppd better.

cant wait to see some 940 BE's around the states...
Uhmm to bad. But i think gaming performance will be quite on par with a few exceptions.

I will wait a bit before i will try a i7 for comparison. The platform is to expensive. I'm gonna wait for the cheaper P55 boards. In some ocations i7's are slower then Penryn or a PHII. i dont know what this is. Low res they are faster or on par with the competition but sometimes they are slower. The Performance is not good enough if you look at the price. And PHII is a nice upgrade. My second pc already has a 780g board. So i only need to upgrade the bios and change the Phenom X3 8450 for a PHII 940 and we are done. If i want a big boost from my intel rig i will need to change almost everything. Of i will have to buy a way to expensive QX9650 to get above the 4.0 GHz.

But i like low power usage so i keep my Q9450 very close to stock volts. I'm gonna do some efficiency tests with the PHII aswell. Like i did with my 5600+ and Q6600. With the Q6600 i needed 0.25v exta to get from 3.2 to 3.550. But then the power i pulled from the outlet jumped 80 watt. With a efficiency of 83% on my PSU the cpu was pulling about 65 watt extra.

Of that same reason i was running my Opteron 170 on 1.27v with 2.8 GHz. If i wanted to do 3.0 i needed 1.35v and performance per watt went down really fast from that point.

I'm gonna do the same tests with the PHII. Its to bad my Abit 780g has no options to lower the voltage (at least on my X3 witch is running 1.25v). There is a chance that i can run the 940 on 1.25v but there is also a chance the bios will adjust the minimum voltage to 1.35v.
