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

GeForce 8600 GT

2008

Why buy it

  • 300% more VRAM for high-resolution textures and newer games (1 GB vs 256 MB).

Trade-offs

  • 2008 hardware with 1 GB of VRAM is already well past its comfortable zone for modern gaming, so it is hard to recommend now.
  • 224.5% HIGHER MSRP
    $159 MSRPvs$49 MSRP
  • Lower G3D Mark per dollar, at 0.9 vs 2.8 G3D/$ ($159 MSRP vs $49 MSRP).
  • 200% higher power demand at 150W vs 50W.

Mobility Radeon X1900

2010

Why buy it

  • Costs $110 less on MSRP ($49 MSRP vs $159 MSRP).
  • Delivers 212.9% more G3D Mark for each dollar spent, at 2.8 vs 0.9 G3D/$ ($49 MSRP vs $159 MSRP).
  • Draws 50W instead of 150W, a 100W reduction.

Trade-offs

  • Less VRAM, with 256 MB vs 1 GB for high-resolution textures and newer games.
  • 2010 hardware with 256 MB of VRAM is already well past its comfortable zone for modern gaming, so it is hard to recommend now.
