It was hot, loud, quite power consuming, there wasn't any microstuttering though. The computer would crash whenever WMP was opened due to not clocking up, and then I also had clocking up issues in games. I spent around 10X more time configuring my setup then I was actually playing games.
With CFX, scaling isn't definite, and you'll go weeks without CFX drivers for new games sometimes. Look, trust me when I say, you would rather a nice overclocking 7970 than two 7850's, as you get none of those issues (Except power consumption is maybe the same), so no microstuttering or waiting weeks for Crossfire profiles, or scaling issues.
