All PCI Express cards are backwards compatible. For example I have used 2.0 cards in a 1.0 slot.

I know 2.0 has twice the bandwidth as 1.0. I don't know what is better about 2.1.

"PCI Express 2.1

PCI Express 2.1 supports a large proportion of the management, support, and troubleshooting systems planned for full implementation in PCI Express 3.0. However, the speed is the same as PCI Express 2.0. Most motherboards sold currently come with PCI Express 2.1 connectors."
