As you can see the P67A-GD80 holds its own against every other P67 motherboard we have tested in the past. In multiple cases it out performs them considerably. Although this is the first time we have used PCMark 7 in a review I can’t wait to see how the GD80 performs against future reviews. All in all the limit of x8 on each of the PCI Express x16 ports wasn’t an issue when testing with our two GTX580’s in SLI. I wouldn’t recommend running a third card, at x4 there is a good chance you will see performance issues there. That third slot could still be used for a lower end card for PhysX or an audio or network card if you are looking for an upgrade in the future.
