Here's the weird thing: I've had a similar experience to OP in terms of losing interest in games...but I still love/fetishize/obsess over game-, overclocking-, and general performance-related stuff...even though I originally got into those things in order to get the best gaming experience possible. Which means that I still spend money to improve my rig, even when I'm not using it to game. Which is absolutely the only thing which makes any serious demands on my equipment. Other than gaming, it's about word processing, internets, and itunes.
Having said that, I find (and I know a lot of other people also find) that improving my rig has become a kind of game in itself, complete with victories, losses, scores and such. A recent upgrade in cooling - new case, new fans, new heatsink - gave me weeks' worth of "fun", taking my rig to a new 24/7 overclock at speeds and volts that I could previously only dream of. Passing (and failing) IBT and P95 Blend was an emotional rollercoaster that basically had a more-or-less happy ending. And took my mind off of much more serious stuff that I really needed a break from. You know, sort of like...yeah. And I know that, at least on this forum, this is not a unique experience.
Having said that, I've recently been "pleased" to find myself getting back into gaming (BC2, Fallout 3, SC2, Forged Alliance). Which means that I get to feel insecure about how much I game, again.
