GeForce 6800 GS

2008

Why buy it

✅Competitive enough if your priority is price, power, or specific feature preference.

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.
❌
25.1% HIGHER MSRP
$249 MSRPvs$199 MSRP
❌Lower G3D Mark per dollar, at 0.8 vs 0.9 G3D/$ ($249 MSRP vs $199 MSRP).

GeForce 8600 GTS

2008

Why buy it

✅Costs $50 less on MSRP ($199 MSRP vs $249 MSRP).
✅Delivers 20.6% more G3D Mark for each dollar spent, at 0.9 vs 0.8 G3D/$ ($199 MSRP vs $249 MSRP).
✅100% more VRAM for high-resolution textures and newer games (512 MB vs 256 MB).
✅Measures 198mm instead of 216mm, a 18mm shorter card that is more SFF-friendly.
