You also have the great NVidia 7950GT installed. Stanford and NVidia are working together to write code that will take advantage of the NVidia's blazing speed, but it is more difficult than dropping assembly code into pixel shaders like on the ATI cards.
The difference between these graphics chips and regular CPUs is incredible. On a normal CPU we see the protein jumps around as it is processed. On my ATI X1650 I see smooth scrolling of the molecule as it is being processed. On a PS3 you can actually see the individual atoms vibrate as it twirls around.
It may be next fall before NVidia cores are released but it is coming.
Also, be careful with Vista. Since it comes with IE7 and has tight security settings then you will be logged in as Admin to install anything. Look here for more info:

and

for running multiple cores of F@H.
You did pull me from the fire with IE7 previously so hopefully I will avoid that.
