not necissarily, look at that high poly 3d mark stuff, its supposed to be rendered real time
i guess, but the 3dmark benchmarks are in a category all their own. they are made expose the limitations the beefiest of computers to see how they stack up against other computers. this is why you dont see and current benchmarks testing to see how well a 7800gt based computer will render a game like half-life, though there will probably be a day when the amount of triangles in any given model wont matter due to insanely robust computers. just like in the 80's when 5 gigabytes on a HDD seemed un-necessary. now anything less than like 20 gigs isnt enough. who knows?
