This is how I felt as well. Had the 560s, got the 660s, and then an 800s. I have a laptop and desktop PC, and was originally using the 560s on the laptop paired with a SoundBlasterX G6 and the 660s w/ a JDS Labs Element III. Once the 800s came into my life, the 560s got sold, the 660s moved to my laptop, and the 800s now live on my desktop :)

I also have 3 pair of their "gaming" headsets (EPOS/Drop ones): PC37X, Game One, and the GSP 370. I think I'm done spending money now...
