Hey Frostysnake,
I use Superior Drummer with my Roland TD-12 kit and it works very well. I would expect it would work very well with the DR-880, but to be honest you probably won't use the DR-880 much once you hear the sounds and purchase some of the MIDI packs available for the Superior Drummer kits.
I don't use any of the sounds or midi patterns available with my Roland kit because the ones the you can get designed for Superior Drummer are that much better.
If you can get it at a good price, I say go for it. You won't regret it.
Hope this helps,
Tom
