I'm thinking about using the second Displayport connection on my Acer Nitro. But my RTX 2080 Ti only has 3 DP ports. That means I need an extra DP output for my Dell 4k. I do have a Maxwell Titan X and a 780 Ti available but this is a non-gaming display and both cards are power-hungry. So I'm wondering if there's a cheap non-gaming GPU that would work with my RTX 2080 Ti. I'd prefer a card with at least two DP ports.
