转个沙桥2600K跑BIGADV的强悍数据，顺便对比一下老I7平台数据，看来新I7性能提升不少啊
I have managed a highest clock of 5.1Ghz @ 1.450vcore, but temps hit 80`c when folding.
Higest clock for these benchmarks will be 4.9Ghz, @ 1.375vcore, ddr3-1600. Temps mid 70`s.
SMP results are in for P6074. Only multiplyer and vcore changed between the runs. Minimum 6 frames per run.
BIGADV preliminary results for P6900
I will test a few different smp WU's down the road. Onto a 6900 now. This of course will take some more time, but will update thread and this post when I am done them.
My 2600K overclocking observations to date for those interested in OC info:
2600K D2 stepping, batch L038A660
Asus P8P67
Corsair 4GB(2x2) DDR3 1600Mhz C8
Corsair H50 w/one Scythe Kaze 1900rpm
running open air bench setup, extra fan over mosfet heatsinks
Firstly, my P8P67 board shipped with bios version 0408, which isn't even listed on the ASUS site. With this bios max OC was 4560MHZ, and IIRC 1.285vcore, LLC max, all other settings stock or auto. This was acheived with lowering bclock to 97 and multi at 47. No matter how much more vcore I supplied I could not reach any higher.
I updated to bios beta version 1053, which enables CPU internal PLL overvoltage, this has so far allowed me to get all the way up to 5.1Ghz.
Many reviews and talk about SB speaks of how much better it OC's with less voltage and less heat. So far the voltage aspect has proven true, requiring 1.45 for 5.1Ghz. Temps are also great up till 4.7 but start going up exponentially afterwards.
Vcore requirements thus far, up to 4.9Ghz I'm good with 1.375v, however to boot 5.0, 5.1 and 5.2 all required 1.450v, nothing less. This caused temps to rise up to 80`c under load, so I have not done any testing other then boot stable and running fah for about one minute.
I'll add to this as I think of things and tinker more.

---------------------------------------
It's not a even comparison since I cannot get my 920 chip to 4.5 Ghz on air. However the comparison gives you an idea of what a older i7 900 series chip vs newer i7 2600 series chip can do. The points per day per watt calculation was based purely on the wattage the cpu was using, not the wattage it's drawing from the wall.
i7 920 Pro's: fairly inexpensive now, good overclocker
i7 920 Con's: higher energy consumption, runs a tad hot
i7 2600k Pro's: great overclocker, lower energy consumption
i7 2600k Con's: higher initial cost
My observation as a folder, I think the i7 2600k in the long run is best bang for the buck when considering the initial release cost of both chips. You can achieve higher PPD for lower power consumption. As a 24/7 folder, every little bit of power savings helps!
I'm cooling the H50's rad through a window, pulling in -10`C air. Clocked at 5.0Ghz and running 68`C. Vcore of 1.48 and power consumption up to 245 watts.
