Verdict

The Nvidia GeForce GTX 660 Ti is a mid-range graphics card based on the 28nm Kepler architecture, featuring 1,344 CUDA cores, a base clock of 915 MHz (980 MHz boost), and 2GB of GDDR5 memory on a 192-bit interface with 144.2 GB/s bandwidth. Main pros include strong 1080p performance relative to its power efficiency (150W TDP), support for technologies like PhysX and GPU Boost, and 3-way SLI capability for multi-GPU setups. However, primary cons include its aging performance in modern DirectX 12/Vulkan titles, limited VRAM for high-resolution textures, and a lack of official driver support for the latest games as it has reached legacy status.
