Runs only at 8x ???

im looking at socket AM2 MOBOS and it says PCIe x16 (electrical x8)

what does the x8 mean ??????????

With PCI-e the socket type and the actual bus are not tied together. In this case it means there is a x16 socket, so you could plug in a video card, but the number of lanes means the speed/bandwidth will only be the equivalent of a x8 PCI-e.

It should also be noted that there is no functional performance difference between operating at 8x and 16x at this point in time.

Not much for a single video card, but there when you are talking about SLI.

True true. But, I think the SLI standard required single card 16x operation splittable into 8x SLI, I don't believe it was ever the case when SLI would split an 8x bus into 2x4x, but I could be wrong.

Even in SLI, though, there is no functional performance difference between 16x-->2x8x SLI on older SLI motherboards and "true 16x" SLI such as the 680i chipsets offer.
