This benchmark is proof that there must be something not quite right with the Mattix Platinum. I don't think it's just the X79 and watercooling, I think it's something else in the design.
Kaap, what do you think?

As far as HD 7970s go the Matrix Platinum is well above average. Having said that they do seem to work in a different way to the ref designs. On this bench they are comming off second best clock for clock but on the Heaven 3 bench they seem to do better.

I think waterblocks would improve things a little but after trying to run this bench on the absolute minimum volts for 1200/1800 clocks the other day and seeeing very little improvement I don't think W/Bs will make a massive difference.

One thing I noticed the other day reducing the volts was reducing the LLC from 100% down to 25% (the minimum) made very little difference to the performance but actually improved stability (I know its supposed to work the other way round). When I tried this on 3dmark11 even @75% there was a big drop in performance.

So to answer your question - Yes there is something very odd about the Matrix and this bench.

It would be interesting to see how the MSI Lightning 7970 goes on this bench using the clocks I posted in my earlier post.

I expect that is because of over voltage and the card exceeding the TDP even with the power limit increased. Either that or it doesn't let the extra voltage and is causing some instability which shows itself as reduced performance.
 
The LLC issue will most probably be GPU Tweak being a nob.
For me it sets back to 75% randomly, sometimes on boot...

If the Titan is £700-£800 then I may sell this 7970 and switch sides, I've had enough of GPU Tweak.

You won't be getting an Asus one then.:D

I have to use GPU Tweak for both NV and AMD - best bit is GPU Tweak has different bugs for each.

I have also noticed LLC setting back to 75%, this is how I found what a difference it makes in 3dmark11 yet on firestrike it was making no difference at all.
 
The biggest improvement for me is I can set a less aggressive fan profile because I was always trying to keep it below 70 degrees to keep it at full boost clocks. That got pretty loud, now I just let it run on towards 80 before really ramping it up.

I use msi after burner for my fan control, because the fan doesnt kick in at all really when gpu gets hot with cards profile.
