Yay! Another computer upgrade!

I don't even know why I bother. I rarely play computer games but upgrade like 2-3 times a year. Just put 2x Radeon 6970s in crossfire in my computer, and a single 6970 in my wife's (my old 5970 didn't fit in her case!). The only thing I really play is Left 4 Dead 2 with my wife and some buddies once in awhile. Anyone else here upgrade just for the sake of upgrading?
