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

GeForce 8600M GS

2008

Why buy it

✅Delivers 100+% more G3D Mark for each dollar spent, at 0.9 vs 0 G3D/$ ($100 MSRP vs Unknown MSRP).

Trade-offs

❌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.
❌150% higher power demand at 150W vs 60W.

GeForce G 105M

2016

Why buy it

✅100% more VRAM for high-resolution textures and newer games (512 MB vs 256 MB).
✅Draws 60W instead of 150W, a 90W reduction.
✅More future proof: Pascal (2016−2021) on 14nm with a newer platform for upcoming games.

Trade-offs

❌2016 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 0.9 G3D/$ (Unknown MSRP vs $100 MSRP).
