Unigine Heaven 4 benchmark

If someone wants to top the charts on the Valley bench three 290Xs should have a good chance but four will be totally useless.;):)

Valley or Heaven?

I found that I got zero scaling past two GPU's in Valley which was odd :/ However Heaven did scale for 3 GPU's

Valley

Valley @1080p is a useless bench for multi GPU setups as it bottlenecks them really bad. What I have noticed with the 290Xs is they are not as fast as the Titans and 780ti's on a one on one basis but they handle a bottleneck better. This means in theory that 3 x 290Xs against say 3 x 780ti's on the Valley bench could come out on top but you are going to need a fast CPU (over 5ghz) to test it.

It still struck me as odd that I got absolutely no scaling on the third GPU, my score was near enough the same as 2 gpu's (or even the same can't rememember exactly)

7*** series cards seem to scale better on trifire in Valley.
 
Valley is a weird benchmark. I might do a run at 5Ghz in it but the volts needed for my Ivy-E chip are cringe worthy.

It is not worth it on NVidia cards, all that happens is you bounce off the GPU bottleneck.

4 Titans score about the same on Valley @1080p or 1600p which is a joke.
 
I just ran a quick benchmark on my newly installed 670. CPU @ 4.5Ghz. 670 @ stock clocks (980/1502Mhz).

Does everything look OK?

Here's my Classified at stock, as you're looking to get one. A touch slower.
