pes2008 geforce 9600

I just bought the notebook card is geforce 9600 512mb, but just to install pes2008, said the procedure went so far as my memory enough to force me into the very poor quality, why ah? Running test software also shows the Arab-Israeli 9600 512mb memory, Wu and three pairs of 5 to play well, not that card is not a question of where to set up ah?
