See where each GPU makes more sense in practice: raw FPS, VRAM, features, power draw, pricing, and long-term headroom.
GeForce 8400
2014Why buy it
- ✅Delivers 100+% more G3D Mark for each dollar spent, at 1.8 vs 0 G3D/$ ($45 MSRP vs Unknown MSRP).
- ✅More future proof: Maxwell (2014−2017) on 28nm with a newer platform for upcoming games.
Trade-offs
- ❌2014 hardware with 512 MB of VRAM is already well past its comfortable zone for modern gaming, so it is hard to recommend now.
- ❌16900% longer card at 170mm vs 1mm.
nForce 750a SLI
2013Why buy it
- ✅Measures 1mm instead of 170mm, a 169mm shorter card that is more SFF-friendly.
Trade-offs
