I was skimming through this thread and thought it was worth pointing out:
(I've double posted this temporarily as I feel its important for prospective buyers with multiple graphic card configs to be aware of this).
"Intel's X58-Express chipset receives 32 total PCI-Express link lanes, but when you consider that the SATA6G and SuperSpeed USB 3.0 take up to six PCI-E lanes there's only one place to borrow them from: graphics. With the Marvell and NEC controllers enabled in a single card configuration there are still sixteen link-lanes remaining for PCI-Express graphics bandwidth, which is more than enough, but a dual-card set would be reduced to 16+8 since these controllers require the remainder"
From the Benchmark Reviews article
I was considering picking up this board until I read that. No full 16x16x lanes for Crossfire or SLI (tri-fire or tri-sli fares even worse) unless you disable the SATA6G and SuperSpeed USB 3.0 controllers (essentially the two main reasons to get this board over the prior generation X58 boards).
I have to say, not impressed. Could Asus not have added something similar to an NF200 chipset to provide more lanes for full graphics bandwidth?
For single GPU users, this is moot though.
I knew going in the SATA 3.0 was a gimmick (maybe it'll work well with SSD's designed to run off of it), but the USB 3.0 will be well worth it when the slew of USB external drives and flash drives that utilize it hit the market.
I'll be curious to see the specs for the RAMPAGE III coming out.
