1280MB VRAM is enough (SLI memory doesnt count as unique thus 2x1280MB is still 1280MB as data is duplicated for each card). Even with texture mods Crysis or Warhead dont hit 1GB VRAM usage until you go past 1920x1200 with 8xMSAA.
The triple buffering in Nivida control panel only affects OpenGL applications/games so it wont affect DirectX games. So triple buffering is stilln to enabled.
