PCI-E 2.0 worth it?

[Predict]

I was looking for a new card and I have never used a pci-e 2.0. If I were to get one is there any thing I should know about them?

Pci-e 2.0 is just a slight upgrade and it should work basically like any other video card you have used. If the motherboard supports PCI-e 2, you are all set
