Quick Answers

Which GPU is faster for gaming right now?

GeForce 7950 GT is the faster gaming card right now. In our data, it leads by 36.3% in average FPS across 50 tracked games in our benchmark data and by 1.5% in PassMark G3D (346 vs 341), so the answer here is pretty clean.

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

GeForce 7950 GT is the safer long-term pick for 2026 and beyond. The case is simple: a 28nm process instead of 40nm and a newer 2014 generation instead of 2011. That makes it the less risky pick as game demands keep moving.

Which GPU is the better buy today?

Radeon HD 6620G makes the most sense to buy today. It is $249 cheaper on MSRP at $50 vs $299, and it leads G3D-per-dollar by 489.4% (6.8 vs 1.2), which is enough to swing the recommendation its way. If you are mainly targeting 1080p and some 1440p, Radeon HD 6620G is the easier value choice. If you care more about 1080p and some 1440p headroom, GeForce 7950 GT has the stronger long-term case.
