The Radeon RX 590 can certainly provide playable performance at 2560 x 1440 as well. In some games, it achieves 60+ FPS with detail settings maxed out. In others, the card requires a bit of compromise.
With the exceptions of Grand Theft Auto and Metro: Last Light, ASRock’s card is faster than our GeForce GTX 1060 Founders Edition. Again, though, XFX’s Fatboy is a little bit quicker.
This is also the resolution where GeForce GTX 1660 Ti’s extra performance makes a big difference in determining whether certain combinations of quality settings run smoothly.
