In case anyone was wondering, it was the GTX 660.

Also, PCI-E is backwards and forwards compatible.

So the 660 requires 3.0 and you guys say I can use 2.0? What?

Wouldn't that mean I'd have to take a performance hit though? Why would it say it needs 3.0 then?

I've never seen the card list 3.0 as a requirement, just that it has it. Think of it in terms of USB 2.0 and 3.0 with the difference that very few if even any cards are capable of maxing out PCIe 2.0 bandwidth so it isn't an issue, especially with a midrange card like that.

OHH. I see what you mean, I thought that was a requirement, but it just means that it has the feature? I thought it was the same with USB, if you plugged a 2.0 into a 3.0 it would work, but not the other way around... At least, that's what some of my devices made me assume.

So basically, USB and PCI are both forwards and backwards compatible? A quick terminology question, I've seen PCI Express and PCIE, are these two different or is PCIE just used to minimize character usage?

PCIE is backwards compatible with previous revisions. A 3.0 card will work on 2.0 and 1.0 and a 1.0 card will work on 2.0 and 3.0
