Quick Answers

Which GPU is faster for gaming right now?

Radeon HD 6320 is the faster gaming card right now. In our data, it leads by 3.4% in average FPS across 50 tracked games in our benchmark data. PassMark G3D leans toward GeForce 305M instead at 151 vs 147, so for this question the real-game FPS result matters more than the synthetic split.

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

GeForce 305M is the safer long-term pick for 2026 and beyond. The case is simple: a 28nm process instead of 40nm and a newer 2015 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 6320 makes the most sense today based on the pricing and value data we have for this matchup. If you are mainly targeting 1080p and some 1440p, Radeon HD 6320 is the easier value choice. If you care more about 1080p and some 1440p headroom, GeForce 305M has the stronger long-term case.
