Verdict
With the RX 6600 running 50% above the GTX 1660 Super — a $296.00 premium — the two cards sit in meaningfully different price brackets. The GTX 1660 Super wins on value unless the extra performance matters for your workload.
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 6600 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.
For most buyers at this price point, the GTX 1660 Super is the practical choice — unless DLSS or a large VRAM advantage specifically matters to your use case.
