My oldest hardware is the rig in my sig, Q6600, P5k-E, GTX285 (replaced 8800gt that died) antec earthwatts 500w psu. Been running the q6600 at 3.4-3.5 ghz at 1.48v since i got it new mid 2007 i think. Still running well and the only upgrade i have ever done is the gtx285. Feeling the need to build a new rig/upgrade soon but buying a house at the moment so dont have the spare cash. Got a laptop running an amd turion dual core RM72 which is a bit slow to boot up but i blame vista for that.
