I ve seen the hype with Mint tried many versions and flavors.
Installing AMD drivers or even installing some software could kill the install easily.Less robust in my opinion than OpenSuse.
After using Mint ,Ubuntu ,Kubuntu ,Simply Mepis and OpenSuse i came to the conclusion that the real deal is Open Suse 12.2.
Best performer in games on Steam running natively.I am talking about CS:S ,TF2 ,DODS.
Also the AMD video drivers installed smooth by simply executing the package.You also have the ati upgrade stuff for this.
Adding the packman repository makes other multimedia stuff possible.
Of course if there is something interesting in another distro you can very well install 2 distroes
But if you take the time to use Open Suse you will see it as a very good alternative.
Using a wattmetter i have discovered that it manages better the APU also opposed to Ubuntu based stuff.
Maybe the tweaked kernel does it opposed to the generic one in Ubuntu.
