GeForce 6600 vs nForce 750a SLI: Pros, Cons & Final Verdict

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

GeForce 6600

2012

Why buy it

  • Delivers 100+% more G3D Mark for each dollar spent, at 0.3 vs 0 G3D/$ ($270 MSRP vs Unknown MSRP).

Trade-offs

  • Less VRAM, with 256 MB vs 512 MB for high-resolution textures and newer games.
  • 2012 hardware with 256 MB of VRAM is already well past its comfortable zone for modern gaming, so it is hard to recommend now.
  • 366.7% higher power demand at 140W vs 30W.
  • 18200% longer card at 183mm vs 1mm.

nForce 750a SLI

2013

Why buy it

  • 100% more VRAM for high-resolution textures and newer games (512 MB vs 256 MB).
  • Draws 30W instead of 140W, a 110W reduction.
  • Measures 1mm instead of 183mm, a 182mm shorter card that is more SFF-friendly.

Trade-offs

  • 2013 hardware with 512 MB of VRAM is already well past its comfortable zone for modern gaming, so it is hard to recommend now.
