Re: SLI Question
SLI allows you to run multiple video cards at once. They are all connected though, so it's sort of like a multi core processor (sorta kinda). Basically, you get around an 80% boost with the first one added, and a 70% boost with the third. That's theoretical mind you. Basically, the scaling isn't perfect, but it's a nice option for upgrading.
CrossFireX is basically the same thing.
