What in the hell is the difference here? 900 bucks and the specs are identical.

The QX6700 has an unlocked multiplier. The Q6700 doesn't.

I still don't see how the $400 difference in price tag is justified though.

The Extreme has an unlocked multiplier

The Extreme is only worth it if your mainboard suffers from some Quad Core FSB limitations (like the first 680i revision or some mATX boards).

Heh, for that much dough just buy a new board... :headexplode:

No kidding.

Maybe it's aimed at those customers (all 2 of them) with those Liquid Nitrogen cooling systems that want to hit 6GHz.....

My mobo taps out at around 1333fsb when using a quad. If my multi was locked, I'd be screwed out of over 200Mhz of cpu overclock.

Sux to be an early adopter because there are now mobo's out there that do well over 400fsb with quads. If I had one, I wouldn't need to bump my multi up to 11 like I do now.

I wonder how well the Q6700 OC's. I have seen Q6600's clock up to around 3.6 Ghz with a G0 stepping and as high as 4.0 GHz. The 10x multi should help things a bit over the 9x on the Q6600. The Q6600 G0 I have does not come close in potential to the QX6700. It was unstable above 3.8 GHz.

Yes, tested on phase, air, and water. :)

The G0 CPU's are much cooler than the B3's. The VID values are about .1 to .15 V lower than the B3 versions. I have been playing with the Q6600, E6750 and E6850 G0 CPU's a little. They do make for some nice upgrades ;)

After all you guys have posted I still don't see the need to pay 900 bucks just for the unlocked multi.

Well, the Extreme CPU series have never been about value, just performance. If you are looking to make the fastest PC, then it may make sense. I have followed the value path for some time, but once I picked up the QX6700, I realized the real potential of a CPU. The E6600 is decent as well as the E6850 or Q6600, but, none of them come close to what the QX can deliver. And, that is first hand experience. If you are looking for balance in your system, then it is not the best choice. If you are looking for the most flexible solution, it certainly fits the bill.
