Difference between pci-e 2.0 x16 and pci-e x16

[Simpson]

What is the difference between these two cards, my motherboard has only pci-e x16 and no 2.0 ?

[SergioSantos]

difference in the bandwidth delivery, but usually does not occupy the current VGA entire width available so I have no problem in 1.0 (or 1.1)

[PreatORiAn]

The two main differences are:

- the bandwidth is doubled in PCI-E 2.0.
- It also doubles the amount of watts that is capable of delivering the slot (75W -> 150W).

[SergioSantos]

like I said before, few VGA come to occupy the bandwidth to deliver even 1.1. At your VGA him on many do not be so complicated that a change of plate does not give you any benefit in that regard
