Quick Answers

Which GPU is faster for gaming right now?

GeForce GT 120 is the faster gaming card right now. In our data, it leads by 4.4% in average FPS across 50 tracked games in our benchmark data and by 5% in PassMark G3D (188 vs 179), so the answer here is pretty clean.

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

GeForce GT 120 is the safer long-term pick for 2026 and beyond. The case is simple: a 14nm process instead of 55nm and a newer 2017 generation instead of 2008. That makes it the less risky pick as game demands keep moving.

Which GPU is the better buy today?

Radeon HD 3450 makes the most sense to buy today. It is $50 cheaper on MSRP at $50 vs $100, and it leads G3D-per-dollar by 90.4% (3.6 vs 1.9), which is enough to swing the recommendation its way. If you are mainly targeting 1080p and some 1440p, Radeon HD 3450 is the easier value choice. If you care more about 1080p and some 1440p headroom, GeForce GT 120 has the stronger long-term case.
