I am still debating picking one of these G0 Q6600's up. I can by the G0 stepping Q6600 at a local store for $279.00. The only problem is I am terribly unsure if I will even notice a difference worth that much money vs. what I have now. Not to mention I don't feel like anything is really slowed down compaired to where it should be. Would be more of a synthetic jump than a practical one it feels like. Let us know how things feel.
