Yeah, I spend too much money on this hobby too. 🙁 In fact, I spend more time messing with hardware than I do the games that I buy it for. About $3,000+ so far me this year. I try to off set some of that by selling off what I don't need, and I also try to take advantage of rebates and deals whenever available. So far, video cards have been my biggest depreciator (ie ti4600 for $399.95 plus tax, sold it for about $200 five months later).
Oh well, it's still cheaper than my old hobby, which was handguns and ammo reloading. A quality Colt 1911, excluding all the tweaks and customizations, will still set you back $600-800. Even more so for my $1000 Gold Cup Nat'l match .45 ACP. Man, I miss those old military days of my youth 🙂
