The exception to this is ebay. Unopened box factory sealed QX6850
sell for $300-$350. It's more a a risk than say Newegg, though both
ebay
and paypal offer buyer protection. I haven't read the fine print.

Less heat for sure.
Performance? Maybe. The thing with unlocked CPUs is you can overclock
_only_ the cpu. The rest of the motherboard can stay stock.
These ebay cpus are priced the same as Neweggs Q9550 today. They are
next gen (45nm VS 65nm, 12MB cache VS 8MB) but locked at 2.83GHz.
As soon as you overclock them, the FSB/Northbridge/Southbridge get
overclocked too. It sounds like the QX6850 goes to 4Ghz easily with no
stress
on the rest of the mb, not so with the Q9550. You won't be able to use
stock cooling.
It's not an easy call, IMHO.

The 48X chipset has good reviews, from a overclock friendly
manufacturer
like Abit or Asus (there are others)

I would get 8GB for video editing, pretty cheap these days.

Then trend in OC seems to be not to OC the memory. Perhaps the
CPU caches make this less important. You could just buy
the fastest memory supported by your mb for not much more money.
