Vista speed

the speed of Ms windows Vista rely very much on graphic card.
before my machine was 3.2pt for graphic ( now upgrade to 4.4pt,see above table )
i found it is really fast during starting machine.
before it took 2mn to go to log in windows
but now it take only 49sec .

before i use graphic card onboard of 133MB , but now i use another graphic card of 256MB.
so i can say that the speed of starting Vista machine rely much on memory of graphic card.
