PCI Express vs. PCI Express 2.0

[JoeBro]

First of all, could a PC that has a PCI Express slot use a PCI Express 2.0 video card? How about the other way around?

Secondly, how are they different?

I looked at the Nvidia website and the highest PCI Express video cards are sorta lame compared to the higher PCI Express 2.0 video card.

Please help.

Cheers,
JoeBro


EDIT: Answer correctly and you'll get a surprise!

PCI-E 2.0 is backwards compatible with PCI-E 1.0a/1.1.

PCI-E 2.0 has double the bandwidth, except all current GPUs are more than content with PCI-E 1.0a/1.1's bandwidth so 2.0 offers no performance increases.

But is PCI Express slots compatible with PCI Express 2.0?

And check this: http://www.nvidia.com/HelpMeChoose/fx/HelpMeChoose.asp

All the PCI Express 2.0 video cards are WAY better than PCI Express ones.

Only PCI-e x16 1.1/1.0A are compatible with PCI-e x16 2.0. PCI-e X8 1.1/1.0A are also compatible, but today you only see them in SLI. The one that's never compatible is PCI-e x1 because of obvious size differences.

Im not using PCI-E x16 2.0, but I am using a 2.0 card (GTX 260) and it works absolutely fine.
