you cant get over 60fps in doom 3 reason: doom 3 has a constant refresh rate of 60hz there for the game can only refresh the worlds model@ 60fps, thats why sli dosnt affect doom 3 at all, theres no way of changing the refresh rate

that is one of the craziest things i have ever heard. interesting

SLi does affect Doom 3.. Say you might be able to run 1600x1200 with 4x AA and 8x AF hehe

It just doesn't affect it if you're not already dipping under 60 fps with 1 card because of the fps lock.
