Verdict
At $259.99, the RX 580 costs about 13% less than the $299.00 GTX 1660 Super. That $39.01 saving is real money, but not so wide that the pricier card is out of reach.
As an NVIDIA card, the GTX 1660 Super gives you access to DLSS 4 super-resolution and Frame Generation, which can meaningfully lift frame rates in supported titles. The RX 580 counters with FSR 4, which is open-source and works across a wider range of games — including some that don't support DLSS. Which ecosystem matters more depends on the games in your library.
