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

GeForce 6600 GT

2012

Why buy it

✅Delivers 100+% more G3D Mark for each dollar spent, at 0.7 vs 0 G3D/$ ($199 MSRP vs Unknown MSRP).
✅Draws 150W instead of 186W, a 36W reduction.
✅More future proof: Kepler (2012−2018) on 28nm with a newer platform for upcoming games.

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.

Radeon HD 6300M

2011

Why buy it

✅100% more VRAM for high-resolution textures and newer games (512 MB vs 256 MB).

Trade-offs

❌2011 hardware with 512 MB of VRAM is already well past its comfortable zone for modern gaming, so it is hard to recommend now.
❌Lower G3D Mark per dollar, at 0 vs 0.7 G3D/$ (Unknown MSRP vs $199 MSRP).
❌24% higher power demand at 186W vs 150W.
