Benchmarks: 1440p

At 1440p the R7 260X and GTX 660 averaged around 40fps, and while this isn't ideal performance, it is playable. For the much more desirable 60fps something like an old HD 7950 or GTX 680 will get the job done nicely, as will the R9 380 and GTX 960.

Keep in mind that Overwatch is a competitive online first person shooter and we found a significant difference between playing at 60fps and say 90fps for example. That being the case, serious gamers will want at least a GTX 970 or R9 390 for competitive performance at 1440p.
