This is great. My board scales back to pci-e 2.0 8x on both of the slots if I plug in 2 graphics cards. Good to know even a 5870 won't be limited by 8x.
excatly my thought regarding my ep45 ud3p. I look forward to a cypress crossfire setup
There's one thing they neglected to test. Load times.
I'm betting there was a significant difference in load times between 1x and 16x. All of this makes sense though, given the large amounts of RAM present on these cards. Most of the textures and geometry are preloaded into the video RAM, so the size of the bus generally won't matter in terms of actual game play once the geometry and textures are preloaded. The only time it matters is when something new has to be written into video memory, which explains why (I'm assuming since it wasn't detailed) average frame rates are as high as they are across the board.
I don't think there is. PCI-e 1x is 100MB/s. Loading up a 1024MB card at that speed isn't going to take any longer than streaming it from the harddrive. Since we're all running at least 8x, this is obviously not a problem.
