They say everythiy old is new again. ArsTechnica, along with several other review sites, are reporting that Nvidia has retooled 3DFX's SLI to be used in their Geforce 6800 series. It lets you put two 6800 vid cards in your computer, and hopefully get double the performance. Nvidia is claiming up to 87% improvement by going to two cards, which means 50% will probably be more typical. The question is, how many people are willing to shell out an extra $300-$500 dollars to get an extra 30fps in Doom3? While I don't think many people will actually use it, it could end up selling a lot of cards. They only have to
think they'll eventually use it. And who knows, while not worth it now, it may make a worthy upgrade path. Six months from now when 6800's drop to 200/300 dollars, it may be a tempting way to extend the life of your gaming rig.
