I'm honestly not 100% sure on the version of PCIE slot I have, but I'm assuming it is version 1 because it says PCI Express x16. I would like to buy a new video card for my computer, but almost all the latest models require a PCIE version 2 or 3. I know they're backwards compatible, but I would really prefer having the full experience of the video card, and would preferably be able to upgrade my PCIE slot to version 3 because I'd like to get the gtx 750 ti. Is this in any way possible without having to buy a whole new motherboard?
