  1. Hello,

    A few things you need to know first:

    For either GPU, PCIE 2 provides enough bandwidth.

    Most current generation GPU's don't take advantage of PCIE3.

    What is your current budget for a graphics card? As well as your complete system specifications? CPU, RAM, SSD, HDD, Power Supply name/model and wattage. Also what resolution do you use? What kind of frame rates are you expecting/wanting in games?

    Your motherboard is PCIE 2 by the way.
