New series of MacBook, MacBook Pro and MacBook Air have Nvidia GeForce 9400M as the graphic chip set. For MacBook Pro, it have the extra 9600M GT for dual graphic display. The future Mac OS X Snow Leopard will support GPU acceleration that enhance the experience. But, readers also found that current Leopard OS also uses GPU acceleration when playing movies.
