Quick Answers

Which GPU is faster for gaming right now?

Radeon HD 6770 is the faster gaming card right now. In our data, it leads by 18.4% in average FPS across 50 tracked games in our benchmark data and by 3% in PassMark G3D (1,271 vs 1,234), so the answer here is pretty clean.

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

GeForce GT 745A is the safer long-term pick for 2026 and beyond. The case is simple: a 28nm process instead of 40nm and a newer 2013 generation instead of 2011. That makes it the less risky pick as game demands keep moving.

Which GPU is the better buy today?

GeForce GT 745A makes the most sense to buy today. It is $30 cheaper on MSRP at $99 vs $129, and it leads G3D-per-dollar by 26.5% (12.5 vs 9.9), which is enough to swing the recommendation its way. Radeon HD 6770 still makes more sense if max raw gaming performance matters more than value.
