That for me?
If so, it is because my old Athlon 64 died a horrible death and it forced me to resurrect my P4 2.4Ghz machine, which was on it's last legs anyway. I was angling for an E6750 anyway, then the new 45nm chips came out for only a very small price increase, so I went that direction instead. And it rules.
My 4.2 Ghz is running at 1.3 volts on vcore and it is running stable at 100% load in Prime95 stress tests for 16+ hours. Temps get up high on 100% load (~70 degrees C) but well within thermal specs for the chip (*Edit* The current gen of temp reporting software are having problems reporting the E8x00 chips correctly, so it is likely my reading I gave are higher than what they really are). Gaming only sees temps of 48-50 deg C on both cores. It is extra special as now there are LOTS of games with dual-core support (though some now even have quad-core support, like Crysis and Alan Wake). My performance bottleneck is now my videocard, which will probably take a month or two before upgrading. It is still enough to run everything I have in 1280x1024 at 40fps+. Ever FEAR.
Overall, for a weeks worth of E8400 experience, I am loving it!
