I dropped about $740 AUD on the guts of my 'new' gaming rig ($125 for 8GB RAM, $135 for motherboard, $295 for i7 2600, $190 for Radeon HD6850), and not only is it a beast at playing all my games, but it's also a strong workhorse when I do Graphic/Audio work and Video encoding (thank you Intel!), something I can't do on a X360, PS3 or Wii.
Oh, and for those who'd try and insult me on spending over $700 for those parts, it'd cost me $400-500 for a X360 or PS3 with a decent-sized drive and/or Kinect/Move, PLUS the $500-1000 it'd cost me to buy a new TV to make playing on a X360 or PS3 look half-decent compared to my old TFT BenQ FP222W (22" Wide) running at 1680*1050 with the HD6850.
So that's easily a $1-1.5K (up to $2K if I got BOTH the X360 and PS3) investment just so I can play games on my couch whilst hogging the TV so others can't use it...
Also, to the one trying to argue that moving from Windows to Linux doesn't make sense when 'simplifying' things - Linux doesn't try to lock you out of things that required Admin/Root access IN an Admin/Root account by using BS like "TrustedInstaller" in Win7...
I've lost track of how many times I've had to hijack control of a folder ~BACK~ from Windows in order to stop crap from fucking me over.
Also, before you try to deride me as a "user who's too big for his boots" for trying to control MY system, I've been building and maintaining computers since I was 7 starting with Windows 95, and even XP didn't give me as much hassles as W7 does when I want to cull the excess crap to make a leaner running system that's lighter on my friggen RAM.
