Then you would have drivers for both types of cards in the same machine. More overhead in my opinion. I did try the 580 and was not impressed as to what I got in return. They are power hungry and you have so many things to do to them to get the most.

 The Nvidia side is just basic plug and play. With 2.0 its even better.  But  then each to his/her own there. Since I work 2 jobs, time is gold to me and have damn little of it right now.
