Well i have a pentium III 450 with a TNT2 32 MB Ultra running at AGP 2x. I am getting an AMD 1.2GHz w/new motherboard, so I will be able to run my video card at AGP 4x. How much of a performance jump will I see between 2x and 4x? Is it at all significant, or not really, or what? Just trying to get an idea of how much faster my card will be now. Thanks
