NF200 doesn't add lanes, it's more like a PCIe switch. It works but it also adds latency.
I see, but that only applies to the storage then or devices using narrower busses.....I'd be interested if the CPU talked to the video cards directly, meaning all 32 lanes, wich ivy bridge will have that feature built into the CPU core...
True, the NF200 is a switch ,and it's also used as the switch inside the GTX590 cards between both GPU's, but hey, it works and that's what matters in the end...
