Uncle Sam came through, and while some home-repair issues have reduced the potency of my gaming dream, I am never-the-less officially getting a new gaming rig!!

If your at all curious about what I went with, you can see it here in all it's "essentials only" glory.

okay, not quite a typical hardware question. but it's terribly unnerving.

my keyboard's spacebar has ceased to operate in the manner it used to. it still seems to function perfectly well, but it has lost the .. i dunno. the keypressiness. somewhat as if it isn't returning to it's fully upright position, but i'm not certain that's actually the issue. i popped it off, with some difficulty, and there doesn't really seem to be anything springy involved. any tips?

So I'm playing with the idea of building a new gaming machine. I've been running XP Pro on an AMD Athlon 64x2 4200+ w/2G of ram and a GeForce 7800GT 256M, and it does alright. But I'm getting to the point where I have to start turning quality setting down, load times are suffering, and certain games get that beloved Viewmaster quality...
