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

FireStream 9250

2008

Why buy it

  • Competitive enough if your priority is price, power, or specific feature preference.

Trade-offs

  • Less VRAM, with 1 GB vs 4 GB for high-resolution textures and newer games.
  • 2008 hardware with 1 GB of VRAM is already well past its comfortable zone for modern gaming, so it is hard to recommend now.
  • 909.1% HIGHER MSRP
    $999 MSRPvs$99 MSRP
  • Lower G3D Mark per dollar, at 1.2 vs 11.8 G3D/$ ($999 MSRP vs $99 MSRP).
  • 130.8% higher power demand at 150W vs 65W.

GeForce GT 640

2012

Why buy it

  • Costs $900 less on MSRP ($99 MSRP vs $999 MSRP).
  • Delivers 912.6% more G3D Mark for each dollar spent, at 11.8 vs 1.2 G3D/$ ($99 MSRP vs $999 MSRP).
  • 300% more VRAM for high-resolution textures and newer games (4 GB vs 1 GB).
  • Draws 65W instead of 150W, a 85W reduction.
  • Measures 145mm instead of 234mm, a 89mm shorter card that is more SFF-friendly.

Trade-offs

  • 2012 hardware with 4 GB of VRAM is already well past its comfortable zone for modern gaming, so it is hard to recommend now.
