SLI Technology permits you to use two video cards at the same time, connected together. You can get about an eighty or ninety percent increase in performance. If you don't use it for shooters, then I doubt that this feature is useful to you, because purchasing two video cards can become very expensive! I would go to Tom's Hardware Guide for a review of the cards that you are looking at, and , perhaps a comparison using the type of s/w that you will be using.

This time I am comparing the GeForce 6600GT to a Radeon X800. They seem to have very similar performance, but the GeForce card I am thinking of is a Gigabyte GV-NX66T128VP that has no fan - translate into QUIET! Is there a reason to favor the X800 over the 6600GT? I do no gaming - just general computer work and occasional video processing. So, I guess video capability is of some importance to me. Also, what is SLI support and is it important to me? If I am overlooking some other alternative, please put me on track. Thank you.
