Quick Answers

Which GPU is faster for gaming right now?

GeForce 840M is the faster gaming card right now. In our data, it leads by 278.1% in average FPS across 23 tracked games in our benchmark data. PassMark G3D leans toward GeForce GT 545 instead at 1,115 vs 1,100, 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 840M is the safer long-term pick for 2026 and beyond. The case is simple: 2 GB vs 512 MB of VRAM, a 28nm process instead of 40nm, and a newer 2014 generation instead of 2011. That gives it more room for heavier textures and higher settings over time.

Which GPU is the better buy today?

GeForce GT 545 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, GeForce GT 545 is the easier value choice. If you care more about 1080p and some 1440p headroom, GeForce 840M has the stronger long-term case.
