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

Quadro FX 4000

2008

Why buy it

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

Trade-offs

❌Lower average FPS than RADEON X800 XT 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.
❌
340.7% HIGHER MSRP
$2,199 MSRPvs$499 MSRP
❌Lower G3D Mark per dollar, at 0.0 vs 0.2 G3D/$ ($2,199 MSRP vs $499 MSRP).

RADEON X800 XT

2020

Why buy it

✅2.0% more average FPS across 50 tracked games in our benchmark data.
✅Costs $1,700 less on MSRP ($499 MSRP vs $2,199 MSRP).
✅Delivers 327.6% more G3D Mark for each dollar spent, at 0.2 vs 0.0 G3D/$ ($499 MSRP vs $2,199 MSRP).
✅Quadro FX 4000 is already obsolete for modern gaming, so RADEON X800 XT is the less risky modern option long term.

Trade-offs

❌Older hardware, 256 MB of VRAM, and weaker feature support mean it will age faster in newer AAA releases.
❌100% higher power demand at 300W vs 150W.

Quick Answers

Which GPU is faster for gaming right now?

RADEON X800 XT is the faster gaming card right now. In our data, it leads by 2.0% in average FPS across 50 tracked games in our benchmark data. PassMark G3D leans toward Quadro FX 4000 instead at 101 vs 98, 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 X800 XT 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 7nm process instead of 55nm, 72 vs 0 ray-tracing units, and a newer 2020 generation instead of 2008. That gives it the more rounded hardware package for newer games.

Which GPU is the better buy today?

RADEON X800 XT makes the most sense to buy today. It is $1,700 cheaper on MSRP at $499 vs $2,199, and it leads G3D-per-dollar by 327.6% (0.2 vs 0.0), so the value case lines up with the gaming result.
