Take a look here at the picture "Fritz Chess benchmark 4.3 (watts atx 12v)":Originally Posted by omninmo
great work chew, this may not be what everyone was hoping to hear but it will surely be of assistance to people reading up to see whther BD fits their needs or not!
Have you any idea of the actual power consumption difference between running 4c/2cu vs 4c/4cu vs 8c/4cu @ same clocks all around, for instance, 4.6Ghz? I am considering an upgrade but at this point im afraid my TX650 would not cut it powering a BD 8c OC plus a 6970 or 6870 CF?

2/4 = 60 watts (100%)
4/4 = 84 watts (140 %)
2/4 turbo = 95 watts (158 %)
8/8 = 101 watts (168 %)
totally power consumption in your scenario (oc and with HD6990) is about 500 watts in peak:

To reach 4/4 @stock in dirt with 2/4, you nearly have to double the power draw. In other games (console ports) its useless, because fps are mostly >60 fps and there is no gain in performance, gpu is limiting.
There are two different methods to get what you want:
1. let the FX-8 or FX-6 work in stock mode and bind the game/the app manually through the task manager to 1357 or 0246 or use a tool like "amd overdrive" or "core affinity resident" to build a profile; you do not need the expensive asus board and simulate the windows 8 task manager in a smarter way than inefficient cu parking+turbo
2. get the FX-8 or FX-6 into 4/4 or 3/3 mode to build X4 oder X3; asus is needed; thats it but you have to go into bios every time
