This is mine, two 7950 giving out 1350khs, 2nd one could be 700+ too but since they are in pc case close together I cant oc it further.

Mining around 6MH/s on 10x 7950's. Hope to add more int he future.
Hi,
Mine are all Radeon HD7970 - Gigabyte Radeon HD7970 OC 3GB DDR5 384bit (1000/5500) (GV-R797OC-3GD)
Ubuntu 64bit
Catalyst 13.3 Beta 3
Hashing is 730KH/s
Donate if my post helped U with getting better performance
Clocks are 1045/1500 (even 1501 memory clock downs hashing to 550 !)

What is the software that you are using to display all that information on the right?
1x 7950 => ~ 530Kh
4x 7970 => ~ 2600Kh
----------------------
TOTAL ~3100Kh
Coming soon:
6x 7970 => ~ 4000Kh
4x 7970 => ~ 2600Kh
----------------------
TOTAL ~3100Kh
Coming soon:
6x 7970 => ~ 4000Kh
4x7850 => ~1590Kh
2x7950 1.1m 400 watt at wall total
that should be around 40k Watts
Actually a bit less, every 3 x 7970 pc i build takes around 900 W on the plug
so [(28+96)/3] * 900 = 37200 W 
I think OP is underestimating the power consumption.
If it is under estimated, my kill-a-watt is broke. Unlikely.
So you are saying that this box:
Box:1
5850 --------- 400.9 khash/s -- 170Watts
5850 --------- 400.9 khash/s -- 170Watts
I3-2100 ------ 20.02 khash/s -- 29Watts
is reading 369Watts in your Kill-A-Watt?
that should be around 40k Watts
28 x 7970 here(around 18Mhses)! And adding 96 (yes, 96!!) 7970 more by end of April
2x7950= 1100
4x5970= 2800
1x7870= 300
=========
4200 for me
4x5970= 2800
1x7870= 300

1x5870

Not much, only 3 6950's hashing away. About 350mh each, don't want to push them too hard.
Dude you can get ~440 easily with a minimal overclock and intensity at 18-19.
Might as well pushem while you got em, they wont be worth much in 2 years and hopefully LTC will be.

Cloned HDDs so everything is the same. Same RAM, same PSUs, same 7950s. Windows 7 using 12.8 drivers.

3.1 MH on 2 rigs. Expanding to about 5.3 MH tomorrow.
Goal is to break 10 MH by the coming weekend.

I think OP is underestimating the power consumption.
I have a rig with a HD 7950 doing 561kh/s (i5 cpu but it's idle most of the time) and my Kill-A-Watt shows 398W-402W
