Alright I was thinking about gettting a 2nd videocard and running in crossfire mode. My question is were do I get the cable to hook them up? The first videocard I got didn't include a crossfire cable. I looked at a demo of how to set it up on tigerdirect and it shows a connector going from 1 card to the other then something comming down from the power supply? If I just buy one and put it in will it automatically set it up to run dual cards? Spec's below.
