Can someone knowledgeable please tell me the different kinds of software that depend on, or benefit from, a high-end graphics card like the Radeon X850 XT - as opposed to a standard card like the Radeon 9600? Is it definitely just action games such as Doom 3 and motion graphics software like Motion 2? If you're buying a G5, but you're not using this kind of software right now, is it best to wait until the day you do use something like Motion 2 before you upgrade your graphics card? (So you get the best value card at the time.) Any tips would be much appreciated!
