Flyby, all of those cards will run SoW for sure in DirectX mode. My wild guess is that there is not much tesselation in SoW as it is pretty much useless in a flight sim. FPS and RPG etc. are a different matter though, as seen in Aliens vs Predator for example.
As of making ice cream..I think the fan of the nVidia is the fastest so it can at least whip cream but beware of the heat
