I'm looking into pulling the trigger on a 280X sometime in the near future, I'm not really too picky on what to spend on one, but I really like the look of the Asus Matrix 280X. What I really want to know is am I going to have any clearance issues on crossfiring them when I get another later? The triple slot seems monsterous, and I just didn't know if anybody has had any experience with them crossfired on something relative to a Asus Maximus Hero board. Any tips will help!
