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 X1800 GTO across 50 tracked games in our benchmark data.
❌Less VRAM, with 256 MB vs 512 MB for high-resolution textures and newer games.
❌2008 hardware with 256 MB of VRAM is already well past its comfortable zone for modern gaming, so it is hard to recommend now.
❌
60.2% HIGHER MSRP
$399 MSRPvs$249 MSRP
❌Lower G3D Mark per dollar, at 0.4 vs 0.6 G3D/$ ($399 MSRP vs $249 MSRP).

Radeon X1800 GTO

2020

Why buy it

✅0.7% more average FPS across 50 tracked games in our benchmark data.
✅Costs $150 less on MSRP ($249 MSRP vs $399 MSRP).
✅Delivers 59.1% more G3D Mark for each dollar spent, at 0.6 vs 0.4 G3D/$ ($249 MSRP vs $399 MSRP).
✅100% more VRAM for high-resolution textures and newer games (512 MB vs 256 MB).
✅GeForce 6800 GT is already obsolete for modern gaming, so Radeon X1800 GTO is the less risky modern option long term.

Trade-offs

❌Older hardware, 512 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 X1800 GTO 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. PassMark G3D leans toward GeForce 6800 GT instead at 142 vs 141, 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 X1800 GTO is the safer long-term pick for 2026 and beyond. The case is simple: 512 MB vs 256 MB of VRAM, the newer upscaling stack, FSR Upscaling / FSR 4 (2025) instead of no meaningful modern upscaling stack, a 7nm process instead of 65nm, and 72 vs 0 ray-tracing units. That gives it more room for heavier textures and higher settings over time.

Which GPU is the better buy today?

Radeon X1800 GTO makes the most sense to buy today. It is $150 cheaper on MSRP at $249 vs $399, and it leads G3D-per-dollar by 59.1% (0.6 vs 0.4), so the value case lines up with the gaming result.
