My Asus Strix R9 380 doesn't have a bridge port. I'm not sure if I need a bridge or not. I called up Asus because I was a noob and I thought that you needed an SLI Bridge. I later found out that SLI is for NVIDIA cards only. But she only talked about the software. I later did some research and found out that multiple graphics cards with AMD Crossfire had used a bridge like SLI. So that really concerned me considering that my card doesn't have any slots for anything... Please someone help me understand.
