Ok here is a new thought for youI can upgrade the graphics card to 1.5GB GDDR5 NVIDIA GeForce GTX 660 how does that one stand? thanks for your help!! Looking to get Alienware computer with Geforce GDDR5 GT 545 graphics card will it run sl ? and if so how will it run? Yes is a Dell machine. I am not so worried about how good the Graphic card is more to the point is will sl run using it? I have had problems with graphics cards before and the general specification on the sl website is as poor as you can get when it comes to information and keeping up with the times. thanks Merc
