Thats true Inspector, but the option is there is what I am saying. There is also the fact that generally Intel releases there top of the line unit first. This I am sure will happen with the 6 core just like any other. A little bit after that release they drop the rest of the line, then a few months after that they update generally on the new line say 6 to 9 months. So by default with a 1366 chip socket you have a year clear for upgrades at the least. If the 1366 chip socket last's anywhere near the time of the 747 socket you have many years. I don't know right now though, as technology is moving so fast, and Intel is on the front line of that movement in many ways, so it may not. Either way I don't see it being fully replaced for 2 to 3 years probably, because as a socket, it is very efficient with tri-channel memory, added PCI-X bus etc. I do think it will be upgraded on the same socket before to long to further widen or make more efficient that memory bus, and of course the addition of USB and SATA 3 is going on right now as well. I imagine intel will upgrade the socket and make those two specific components more in place added to there bus capabilities or at least operational figures and methods.
Which basically leaves you overall with an awesome system that can be upgraded for some time, and in anyone's outlook will give you an awesome system ready for the next course if you get my drift. Not to mention the secondary CPU's will be hundreds cheaper than the top of the line. Think about the current one and the I7 920, the top of the line for first release is still 999 until the 6 core is released, where the I7 920 is 289. Even if your strapped you can save 20 a month for a year and get the upgrade, while everything else (which are all solid components), can just stay the same. So basically financially strapped or not you win an awesome system for a year to two years for free, which can also by default stay top of the line with a very low cash flow.
