So I recently installed my new cards.

I'm getting BSOD inside windows 7, the bluescreen says something about ATI and also is at bottom dumping physical memory.
So I'm now going to try just 2x 7950 gpu's.

In total I have 2x 7950 and 1x 7970, I might end up selling the 7950's or the 7970.

So as I said 2x 7950 BSOD, I had logging apps running(speedfan or gpuz or HWinfo64).

NOW after not running any logging software the cards are stable.

I got 20fps & 505points with one 7950 in Heaven 2.5, with 2x I get 37.7fps and 948points, so scaling is amazing and working properly
 
Nice boost, seems odd that monitoring s/w is making them act up though, I'll have to run mine through heaven 2.5, see what I get :)

both cards are 6950 2Gb btw

you are correct sir.

I did also bench AvP with even better scaling then Heaven.

Crysis2 only gave 56% and 65% scaling on 2 maps compared to 88-90% on Heaven and AvP
