At almost 2 years old, the RX 6750XT is still very much a potent 1440p gaming card, the one exception being if you intend to run heavy ray tracing effects. It even does some 4k plain rasterization well too, depending on title. Unless you have a specific need outside of those parameters that the 6750XT doesn't fill, you should be good.
