Quick Answers

Which GPU is faster for gaming right now?

GeForce GT 320 is the faster gaming card right now. In our data, it leads by 47.9% in average FPS across 50 tracked games in our benchmark data and by 3.5% in PassMark G3D (470 vs 454), so the answer here is pretty clean.

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

GeForce GT 320 is the safer long-term pick for 2026 and beyond. The case is simple: 1 GB vs 512 MB of VRAM, a 14nm process instead of 40nm, and a newer 2017 generation instead of 2012. That gives it more room for heavier textures and higher settings over time.

Which GPU is the better buy today?

Radeon HD 7640G makes the most sense to buy today. It is $29 cheaper on MSRP at $50 vs $79, and it leads G3D-per-dollar by 52.6% (9.1 vs 5.9), which is enough to swing the recommendation its way. If you are mainly targeting 1080p and some 1440p, Radeon HD 7640G is the easier value choice. If you care more about 1080p and some 1440p headroom, GeForce GT 320 has the stronger long-term case.
