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

GeForce 6800 GT

2008

Why buy it

✅Draws 150W instead of 300W, a 150W reduction.

Trade-offs

❌Lower average FPS than Radeon X1900 GT across 50 tracked games in our benchmark data.
❌2008 hardware with 256 MB of VRAM is already well past its comfortable zone for modern gaming, so it is hard to recommend now.
❌
33.4% HIGHER MSRP
$399 MSRPvs$299 MSRP
❌Lower G3D Mark per dollar, at 0.4 vs 0.5 G3D/$ ($399 MSRP vs $299 MSRP).

Radeon X1900 GT

2022

Why buy it

✅0.7% more average FPS across 50 tracked games in our benchmark data.
✅Costs $100 less on MSRP ($299 MSRP vs $399 MSRP).
✅Delivers 37.2% more G3D Mark for each dollar spent, at 0.5 vs 0.4 G3D/$ ($299 MSRP vs $399 MSRP).
✅Better long-term bet: RDNA 3.0 (2022−2026) on 5nm gives it a newer hardware base for upcoming games.

Trade-offs

❌100% higher power demand at 300W vs 150W.

Quick Answers

Which GPU is faster for gaming right now?

Radeon X1900 GT is the faster gaming card right now. In our data, it leads by 0.7% in average FPS across 50 tracked games in our benchmark data and by 2.8% in PassMark G3D (146 vs 142), so the answer here is pretty clean.

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

Radeon X1900 GT is the safer long-term pick for 2026 and beyond. The case is simple: the newer upscaling stack, FSR Upscaling / FSR 4 (2025) instead of no meaningful modern upscaling stack, a 5nm process instead of 65nm, 84 vs 0 ray-tracing units, and a newer 2022 generation instead of 2008. That gives it the more rounded hardware package for newer games.

Which GPU is the better buy today?

Radeon X1900 GT makes the most sense to buy today. It is $100 cheaper on MSRP at $299 vs $399, and it leads G3D-per-dollar by 37.2% (0.5 vs 0.4), so the value case lines up with the gaming result.
