Quick Answers

Which GPU is faster for gaming right now?

GeForce GTX 460 v2 is the faster gaming card right now. In our data, it leads by 112.7% in average FPS across 50 tracked games in our benchmark data and by 0.5% in PassMark G3D (2,016 vs 2,006), so the answer here is pretty clean.

Which GPU is the safer long-term pick for 2026 and beyond?

GeForce GT 645 is the safer long-term pick for 2026 and beyond. The case is simple: 2 GB vs 1 GB of VRAM, a 28nm process instead of 40nm, and a newer 2012 generation instead of 2011. That gives it more room for heavier textures and higher settings over time.

Which GPU is the better buy today?

GeForce GT 645 makes the most sense to buy today. It is $100 cheaper on MSRP at $99 vs $199, and it leads G3D-per-dollar by 100% (20.3 vs 10.1), which is enough to swing the recommendation its way. GeForce GTX 460 v2 still makes more sense if max raw gaming performance matters more than value.
