PC - Question on PCIe slots - View Post

jefforange89 said:

So, with USB3 coming devices coming out soon, I'd like to add support for it to my computer, preferably without needing a new motherboard - ASUS (and presumably others as well) is releasing a PCIe expansion card with USB3 (and SATA6) slots, so I'll probably pick one up, though I had a few questions regarding PCIe slots first

- ASUS' card, at least, is supposed to be for PCIe x4 slots - would it work in PCIe x16 slots as well?

- With my motherboard, if I have something in both PCIe x16 slots, they'll both actually only run at x8 - could this end up being a bottleneck for my 4870 (and future 5870 or 5970, depending on which I get), or would the extra bandwidth just be superfluous?

Why do you care about USB3.0 support at all ?

Imho you shouldn't worry before you actually have some piece of hardware that would use it.
