I have a question regarding SLI. Do I need a special PSU to run an SLI rig? (would a Fortron Bluestorm 500 be equipped to handle SLI? My second question is: you apparently need somrthing like an SLI bridge to connect the GPU's. Is that packaged with the graphic card? With an SLI mobo? will I have to buy t separately? I ordered an ASUS 7800GTX TOP, and am considering adding another one in one or two months (love the upcoming nvidia drivers which will make mixing and matching nvidia GPUs possible). So will I have all components to build a SLI rig or do I need extra/other parts?
