Hi Rob,I'm surprised at the dual 480X scores. I get around 13 secs with dual 280X cards. I thought a single 480X card was between 50% and 80% faster than a single 280X.
Admittedly this is early days but I'd hope the performance would get significantly better.
I have a slightly faster CPU (4Ghz?) and 32GB but the BruceX benchmark is specifically designed to test the GPU performance by doing lots of visual effects stuff.
Whilst a very slow processor and very little RAM will make a difference, its not going to be too much worse off for the benchmark as it doesn't hit the CPU much or RAM or Disk.
The fact you have made it work at all is good, but there is clearly lots of performance improvements to be got out of the cards.
I'll stick with the dual 280X cards for the moment.
This is fine.
It should show two "AMD Radeon HD....." cards in About This Mac not one though.
The PCIe Lane width is due to how your overall PIC bandwidth is allocated. Your board has allocated it in this proportion.
You also need to update your profile with your hardware.
