Verdict

The Gigabyte GeForce GTX 1660 Super Gaming OC is a high-performance mid-range graphics card built on the NVIDIA Turing architecture, featuring 1,408 CUDA cores and a factory-overclocked boost clock of 1,860 MHz. It is equipped with 6GB of high-speed 14 Gbps GDDR6 memory on a 192-bit interface, providing a substantial 336 GB/s memory bandwidth that rivals the GTX 1660 Ti. Its primary advantages include excellent 1080p gaming performance, an efficient Windforce 3X triple-fan cooling system with alternate spinning fans for superior thermal management, and a dedicated Turing encoder for high-quality streaming. However, it lacks hardware-accelerated ray tracing and DLSS support found in newer RTX models, and its 280mm length may be too large for some compact computer cases.

What customers like about GIGABYTE GeForce GTX 1660 Super Gaming OC?

  • Excellent value for the price, offering performance nearly identical to the more expensive GTX 1660 Ti
  • Top-tier cooling performance provided by the triple-fan Windforce 3X cooler, maintaining very low temperatures under load
  • Quiet operation with an idle-fan-stop feature that keeps fans completely off during light tasks
  • Strong 1080p gaming performance, capable of reaching over 60 FPS in many modern titles at high settings
  • Includes a protection backplate that adds structural integrity and a cleaner aesthetic
  • Relatively low power requirements, making it suitable for builds with power supplies as low as 450W

What customers dislike about GIGABYTE GeForce GTX 1660 Super Gaming OC?

  • The backplate and overall shroud are made of plastic rather than metal, which some users feel looks less premium and does not aid in heat dissipation
  • Minimal RGB lighting features, limited only to a backlit brand logo on the top of the card
  • The card is quite long due to the triple-fan design, which may cause clearance issues in smaller cases
  • Lacks hardware-accelerated Ray Tracing (RT cores) and DLSS, features found in newer RTX series cards
  • Not ideal for native 1440p or 4K gaming on demanding modern titles without significant setting reductions
