Hey guys.

I was getting 1080 hash/sec with just 5970 and 5870 (on CGMiner) around 350hash/sec for each GGPU

 now I switched to:

7970
6870
5970

and only getting 1400 hash/sec (on DiabloMiner because it is required for 7970).

What am I doing wrong?

7970 gets about 550 at stock clocks.  6870 gets 260-280 and 5970 gets 640-680mh/s.

5000 series cards do extremely well with SDK 2.1, but since you have a 7970 in the mix you have to use SDK 2.6 which isnt so good.

I get 998mh/s from my setup (mild undervolt too)  430watts right now at the wall.

7970@975mhz
6550@650mhz
5870@885mhz

Any special flags you use for Diablo?

for CGminer I use these:

-v 2 -w 256 -g 4 -k phatk --gpu-memclock 300 --auto-fan --temp-target 69 -I 7

can I do the same for Diablo?
