    Was a lot better investment than spending money on the 11 series. Have it paired with a 3900 and have yet to see anything it can't do right now.

    I’m not sure why, but the piece was dead on arrival. We put it in and it didn’t work, resulting in us getting a new motherboard and processor. It was super disappointing.
