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

GeForce 6100

2017

Why buy it

✅300% more VRAM for high-resolution textures and newer games (512 MB vs 128 MB).
✅Draws 30W instead of 365W, a 335W reduction.
✅More future proof: Pascal (2016−2021) on 14nm with a newer platform for upcoming games.

Trade-offs

❌Lower PassMark G3D performance (27 vs 33).
❌2017 hardware with 512 MB of VRAM is already well past its comfortable zone for modern gaming, so it is hard to recommend now.
