Quick Answers

So, is Radeon PRO W6600X better than GeForce GTX 1660 Ti?

Yes, but this is not really about a huge raw performance gap. The broader synthetic picture is also very close at 12,747 vs 13,113 in G3D Mark. The bigger reason to prefer Radeon PRO W6600X is the overall package: you are getting a newer generation, FSR upscaling.

Which one is more future-proof for 2026 and beyond?

Radeon PRO W6600X is the more future-proof choice for 2026 and beyond. You are getting a newer 2021 generation instead of 2019, more VRAM at 8 GB instead of 6 GB, better upscaling support with FSR Upscaling / FSR 4 (2025) instead of no meaningful modern upscaling stack, and a 7nm process instead of 12nm. That extra memory headroom makes it the safer pick for newer games, heavier textures, and higher settings over time.

Which one is the smarter buy today, not just the cheaper card?

GeForce GTX 1660 Ti can still make sense if you find it at the right price, especially around $279 MSRP. Radeon PRO W6600X is still the smarter buy for most people, though, because the raw performance is close while the overall package is cleaner. Radeon PRO W6600X is about 150.5% more expensive on MSRP at $699 MSRP versus $279 MSRP, and you are getting 2.9% higher G3D Mark. Moving to $699 MSRP gets you newer hardware, and FSR upscaling.

Is GeForce GTX 1660 Ti still worth buying for gaming in 2026?

Yes. GeForce GTX 1660 Ti is still a strong gaming card in 2026: it is very strong for 1080p, good for 1440p, and more limited at 4K. Price is really the swing factor here. If you find it at or below $279 MSRP, it remains a very sensible buy. Radeon PRO W6600X is still the safer recommendation for most fresh builds because it offers a cleaner overall package with newer hardware and FSR upscaling.
