hi, im just curious. What are the benefits of dual graphics? are people just doing mulitiple cards for higher resolution gaming? I am creating a HTPC for an HDTV so the resolution is only up to 1080p, which is enough for me, and my gtx 670 all current games on max settings at a decent framerate, though im not sure if it runs them at 60fps, but since hdtv's dont really support higher frames than that, I dont see the purpose of having 100+ fps. So for my situation, a single card should suffice? Or could I benefit in anyway with another graphics card?
Up to the task? Thats about about as good as a gaming processor gets. Just shut down hyperthreading. It causes minor issues. At least for some it does.
The point of SLI or Crossfire is exactly the same as a single card: higher frame rates and more detail. Thats the difference between just having dual graphics cards and having SLI/crossfire. In SLI/Crossfire, the cards work together on one display to produce greater output than one card alone. Plain old dual cards would be to display on two monitors.
