Hi people, I hope someone can be of help. I used to have my 2080ti with a CoolerMaster vertical mount and PCIE Geb 3 riser cable. Is anyone using a 3080 on vertical mount with a PCIE Gen 3 cable? I also have a 5800X and X570 Taichi board, so was wondering if I would be losing performance by not using a Gen 4 cable. Thanks.
