Hello,

First off, I wasn't sure whether to put this here or in graphics cards. If it should be in graphics cards, feel free to move it.

Here is my current motherboard. In the specs, it has:

Quote:

PCI Express 2.0 x16 1 PCI Express x16 1 x PCI Express x16 slot, running at x4 (PCIEX4)

Furthermore, on the manufacturer's website, it shows:

Quote:

# 1 x PCI Express x16 slot, running at x16 (PCIEX16) (The PCIEX16 slot conforms to PCI Express 2.0 standard.) # 1 x PCI Express x16 slot, running at x4 (PCIEX4)

I'd like to replace my 470 with two 460's. I've read from a few places that the drop from x16 (or x8) to x4 is negligible (~5%), which is fine by me until I can afford an 8x/8x board. However, those tests were with PCI Express 2.0. Forgive my lack of knowledge on PCI-E tech, but is the x4 slot on my motherboard 2.0? If not, how much of a difference is there between 2.0 and whatever mine is?

Thanks in advance.
