Just the one in my sig called "gaming rig", might be a little dated now a days as I built it back in Feb 08 but still handles any game I throw at it and yes! It can/does play Crysis! ... and Crysis: Warhead.
Figured why bother with GPU updates if the 9x00 series was a modified 8800 series and now my quad probably would be the bottleneck with the latest gpu so just waiting to get an i7.
