Performance of Apps installed on SD card? What SD to get for games?

[sprtfan]

Maybe it doesn't make a difference anymore, but back when I used to run Android off of an SD card on my Nook, the SD card made a big difference in performance. If I remember right, a SanDisk Class 6 out performed most of the Class 10 cards since write speed was not the only thing that was important. Would this still be an issue or is running an OS from the SD card enough different than running an App that it wouldn't make a difference? or have SD cards came far enough that most should work fine? Thanks
