If you stumble your way through Intel's website you can find where to buy them ( I think its pre-order) but what I saw was the q9450 was about $400 and the q9550 was about $600.
Thank you for the links.It seems the Q9550 might be the best performance to cost quad core from looking at the specs,might clock high,somewhat future proof and still not over $1,000 like the Qx9650.
