  1. Hi, everyone, I've a quick question about PCI Express

    Are PCIe x16 cards automatically 2.0? Or are there PCIe x16 1.0 and 2.0 cards?

    There are both 1.0 and 2.0, but the 2.0 cards are backwards compatible with pci e 1.0 slots.

    2.0 is backwards compatible with 1.0 and they are twice as fast but run at 1.0 speeds on 1.0 slots. 1.0 works on 2.0 slots but only operates at 1.0 speeds.
