Hello everyone! This is my first post here and I just have a few questions about running two graphics cards. As of now, I have an AMD FX-6300 CPU and an asus AMD Radeon HD 7850 2GB along with 8 GB of ram. I want to boost my performance for the new games that are coming out (BF4, Watchdogs, ghosts), and I was wondering if simply buying another asus AMD Radeon HD 7850 2GB would be a good idea. I have seen them for really cheap recently, but I have never run more than one gpu at a time, and I have a lot of dumb questions about it. I was wondering if I could do so with only one monitor. Also, would it give a dramatic performance increase? Would I need to get a bigger power supply? (mines 600w). Would I need to do anything more than simply popping it in and hooking it up with the rest of my system? Thank you all!
