Why GFX card with more RAM?

This one works for OpenGL games only IIRC. This could have changed though as I did not use NV recently.

Enabling Triple Buffering for OpenGL-based games such as Doom 3, Quake 4, Prey or Enemy Territory: Quake Wars is very simple - go to your graphics card's control panel and enable it from there. However this won't work for enabling Triple Buffering in Direct3D-based games, which are the bulk of modern games. Instead, you will need to use a utility called Direct3D Overrider (D3DOverrider) which comes with free RivaTuner utility.

Many reports of "terrible fps" are caused by not switching it On imho having vsynk On.
On my ATI card I have 30 fps with triple buffering off and 40-50 fps if it is on. I force it via creating a game profile for CloD in ATI Tray Tools.
I guess this allows my card to be 98-100% loaded according to a monitor when many others report 70% load only.

PS. Moreover I noticed if vsynk is switched on both in game and in drivers it results in further fps reduction because of some conflict. I prefer to run the game with vsync off recently to get rid of all these limitations altogether and stop screen tearing by reducing graphics settings, overclocking and other system optimisations.
