Quick Answers

Which GPU is faster for gaming right now?
Radeon RX 780 is the faster gaming card right now. In our data, it leads by 21.2% in average FPS across 50 tracked games in our benchmark data and by 2.2% in PassMark G3D (7,658 vs 7,495), so the answer here is pretty clean.
Which GPU is the safer long-term pick for 2026 and beyond?
Radeon RX 780 is the safer long-term pick for 2026 and beyond. The case is simple: the newer frame-generation stack, FSR Frame Generation + AFMF (2023) instead of FSR Frame Generation (2023), a 5nm process instead of 14nm, 60 vs 0 ray-tracing units, and a newer 2024 generation instead of 2018. That gives it the more rounded hardware package for newer games.
Which GPU is the better buy today?
Radeon RX 580X makes the most sense to buy today. It is $270 cheaper on MSRP at $229 vs $499, and it leads G3D-per-dollar by 113.3% (32.7 vs 15.3), which is enough to swing the recommendation its way. If you are mainly targeting 1080p and some 1440p, Radeon RX 580X is the easier value choice. If you care more about 1080p and some 1440p headroom, Radeon RX 780 has the stronger long-term case.
