If you’re on a low budget and want a GPU that supports 1440p then the best value would be the RX 6750 XT and RX 6700 XT 12 GB as they’re priced just below 300 dollars, if ever one manages to get them. They are well-suited to the given price class. Absent those, the RTX 360 12 GB priced at $265 is a reasonable recommendation in terms of value.
