I would stay away from OCZ products as although they make very fast SSDs, they aren't very reliable and the company is sinking as we speak. I would go with Samsung or Crucial. You don't list your monitor resolution, but unless you are playing on 3 1080p LCDs, you won't need that gpu set up. I never recommend SLI or Crossfire cuz they have several issues anyway. If you aren't gaming on a tri LCD setup, go with the fastest single card you can get, a 7970 GHZ or 680gtx.
BTW, which CPU do you recommend?
