I kept mine, and I'm glad I did. I have it hooked up to my old monitors, old keyboard etc etc My motherboard died recently, so it got some use while I fixed my main rig. Hard to believe it is already so out dated, yet still is pretty fast for most tasks. Q6600 has some staying power for sure.

I plan on upgrading my x58 as soon as the x79 boards are a bit more mature, so the trickle down effect will be in full force.
