Quick Answers

Which GPU is faster for gaming right now?

Radeon R6 M255DX is the faster gaming card right now. In our data, it leads by 0.8% in average FPS across 50 tracked games in our benchmark data. PassMark G3D leans toward GeForce 9800 GX2 instead at 613 vs 605, 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?

Radeon R6 M255DX is the safer long-term pick for 2026 and beyond. The case is simple: 512 MB vs 2 MB of VRAM, the newer upscaling stack, FSR Upscaling / FSR 4 (2025) instead of no meaningful modern upscaling stack, a 28nm process instead of 65nm, and a newer 2014 generation instead of 2008. That gives it more room for heavier textures and higher settings over time.

Which GPU is the better buy today?

GeForce 9800 GX2 makes the most sense today based on the pricing and value data we have for this matchup. If you are mainly targeting 1080p, GeForce 9800 GX2 is the easier value choice. If you care more about 1080p and some 1440p headroom, Radeon R6 M255DX has the stronger long-term case.
