My rig at home ran everything I threw at it.
Phenom II quad 3.5ghz
AMD 6770, I think it was from diamond
4 gigs of ram
Some old salvaged case from an old build
Heavily modified xtremegamer soundcard(full cap swap and changed out opamps, plus shielding on the card)
I tend to play the more competitive games(source, q3, lol, cod4, etc) with it so I never saw the need for an insane amount of power.
