See where each GPU makes more sense in practice: raw FPS, VRAM, features, power draw, pricing, and long-term headroom.

GeForce 6800

2014

Why buy it

✅45.9% more average FPS across 50 tracked games in our benchmark data.
✅100% more VRAM for high-resolution textures and newer games (256 MB vs 128 MB).
✅More future proof: Maxwell (2014−2017) on 28nm with a newer platform for upcoming games.

Trade-offs

❌2014 hardware with 256 MB of VRAM is already well past its comfortable zone for modern gaming, so it is hard to recommend now.
❌
498% HIGHER MSRP
$299 MSRPvs$50 MSRP
❌Lower G3D Mark per dollar, at 0.4 vs 2.1 G3D/$ ($299 MSRP vs $50 MSRP).

GeForce 8400M G

2014

Why buy it

✅Costs $249 less on MSRP ($50 MSRP vs $299 MSRP).
✅Delivers 455.7% more G3D Mark for each dollar spent, at 2.1 vs 0.4 G3D/$ ($50 MSRP vs $299 MSRP).

Trade-offs

❌Lower average FPS than GeForce 6800 across 50 tracked games in our benchmark data.
❌Less VRAM, with 128 MB vs 256 MB for high-resolution textures and newer games.
❌2014 hardware with 128 MB of VRAM is already well past its comfortable zone for modern gaming, so it is hard to recommend now.

Quick Answers

Which GPU is faster for gaming right now?

GeForce 6800 is the faster gaming card right now. In our data, it leads by 45.9% in average FPS across 50 tracked games in our benchmark data and by 7.6% in PassMark G3D (113 vs 105), so the answer here is pretty clean.

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

GeForce 6800 is the safer long-term pick for 2026 and beyond. The case is simple: 256 MB vs 128 MB of VRAM. That gives it more room for heavier textures and higher settings over time.

Which GPU is the better buy today?

GeForce 8400M G makes the most sense to buy today. It is $249 cheaper on MSRP at $50 vs $299, and it leads G3D-per-dollar by 455.7% (2.1 vs 0.4), which is enough to swing the recommendation its way. If you are mainly targeting 1080p and some 1440p, GeForce 8400M G is the easier value choice. If you care more about 1080p and some 1440p headroom, GeForce 6800 has the stronger long-term case.
