Here is something I've been thinking about. People constantly talk about doing SLI or Crossfire to increase performance however it comes with problems. Drives can be a pain to install (AMD), two video cards can cause micro stutter or sometimes worse performance and other problems. So my question is whats the point? Why not just get a single video card with two GPU's like the 6990 or 590? Wouldn't that give you the same power but without the problems of SLI o Crossfire. You would still have the same memory since double video cards doesn't increase memory. You would still have the power of two GPU's except it would be on a single card rather then double cards and by the time you buy dual video cards the price difference wouldn't really be that great. So why don't more people buy a single video card with dual GPU's it would seem better then two single GPU cards paired in SLI or Crossfire.
