4x Sapphire HD 7970 OC Review: Quad CrossFireX Madness!

mortisboy · May 7, 2012, 12:45 PM

Hello people,

We are testing 4x Sapphire 7970 Dual-X in CrossfireX configuration.
There are a lot of games and bench tested and comparison with 1,2,3,4 cards setup.
I know that everything is in Greek, but the Charts are speaking by themselves!

Enjoy

So the 4th is practically useless in games, and adding a 3rd is only a marginal improvement...

No temperatures?

Wow that's pretty crazy that only the synthetic benchmarks can take advantage of more than 2 GPU's. I wonder if the CPU is a bottleneck when you see the performance go down with 3+ cards? Crossfire scaling is pretty awesome most of the time though!

A Core i7 3960X at 4.5GHz is a bottleneck?
