Quick Answers

Which GPU is faster for gaming right now?

RADEON X800GT is the faster gaming card right now. In our data, it leads by 1.0% in average FPS across 50 tracked games in our benchmark data and by 8.1% in PassMark G3D (80 vs 74), so the answer here is pretty clean.

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

RADEON X800GT is the safer long-term pick for 2026 and beyond. The case is simple: a 7nm process instead of 14nm, 60 vs 0 ray-tracing units, and a newer 2020 generation instead of 2019. That gives it the more rounded hardware package for newer games.

Which GPU is the better buy today?

RADEON X800GT makes the most sense to buy today. It is $39 cheaper on MSRP at $160 vs $199, and it leads G3D-per-dollar by 34.5% (0.5 vs 0.4), so the value case lines up with the gaming result.
