Technology is dated just a bit, though not much. If I were more familiar with how the euro was doing, I would suggest an answer, but i'm just not sure.
The extreme edition processors were very highly priced, but only because they had an unlocked multiplier, and were great overclockers. Beyond this, after the first batch if i7s came out, the processor lost its allure at said price, because even lower end i7 processors could outdo it.
9800GTs can still max out everything today pretty nicely, so that is a good thing.
With what I see here, it comes down to 2 things:
1. Because of the cooling technology used, and the processor/mobo combo, overclocking is a big deal here. Do you overclock at all? and if you are, would you push it's limits? If you answered yes, then that is a major plus here.
2. What kind of operating system is installed, if any? For instance, if this came with a win7 PRO 64-bit, with COA, that would greatly influence my decision.
In the long run, you can get a great amount of expandability with the high-wattage power supply, so this would last you a while.
I would pay $1300 for this machine, myself. I am not a huge overclocker, though. I get to 4GHz, and say "meh..."
