R9 280x 144hz

Okay, so to prefice, I know people will say my GPU isn't equipped for a 144hz monitor, but I'm mainly only going to use it for CSGO and other easy games. But anyways, what would be my best bet to try and get 144hz for it? There are two mini display port ports, a dual-link dvi-i and a hdmi port, and I heard HDMI 1.3/upwards wouldn't work for 144hz because of it being an older card. So what can I do?

When I had a 280x the only sockets that could hit 60hz 3440x1440 were the display ports.
144hz 1080 should have similar bandwidth requirements.

HDMI was 30hz and iirc div was 52 before tearing.
