I do find the hardcore PC gaming crowd tiresome (you know, if it's not 120FPS constant it's bullshit), I've pretty much always been a console gamer (bar a couple of games - HL2, Doom 3, and of course FM, etc). I can't deny however that I'd love a really good rig, and it's something I'm gonna do when I've scrounged together enough moolah - the aim is a decent gaming rig for the things that will show off it's power, that I can also use as an entertainment centre effectively - movies, music, etc, hooked up to a decent TV and sound system.
That dreams becoming more pressing as my 2006 built PC falls apart. Still having to fudge along with a dying HDD.
