  1. If it is the mini tower no problem as long as you upgrade to a bigger PSU! http://www.dell.com/us/dfb/p/optiplex-755/pd
  2. I hope it's the mini tower version - otherwise you can pretty much forget it.

  8. Not really the AMD line is all ver 2.1 cards which might have issues running on your board.

    Upgrading your PSU is easy. Just get the one I suggested and then take your pick of any single-plug GPU for gaming. And when installing make sure you keep track of which connections go where.

    I don't forsee PCI 3.0/2.1 cards being an issue, they are all backwards-compatible.
