Overall, the board is good...but I think the BIOS is very buggy....
Sometimes it won't load into windows at 370 MHz FSB, and at other times, It will happily prime all day at 400 MHz FSB....
Also there is an issue with the RAM once you exceed a certain FSB...you have to run your RAM slower than what it can normally do else it won't get into windows....
The cooling for the board is actually extremely good apart from the crap thermal interface. Ditch it and use some AS5 and it works like a dream. Totally passive and remains below 45*C under load.
I think ASUS needs to make the BIOS more mature, and this board will be a winner.
And Harshal bhai, it doesn't reboot randomly but when you restart from the shut down menu, from the BIOS or simply press the reset button, rather than restarting normally it'll power off completely and then turn back on after 1-3 seconds. Annoying, but isn't a real issue and is normal with these boards.
As for 3D Benchmarks, i can't really provide a fair comparison right now. I used to get 11k in 3DM05 with my opteron 165 @ 2.9 GHz and my X1800XT @ 640/850, but that was under water cooling and now i'm on stock cooling with my card.
And as far as how I got the CPU....well I can't comment on that. Just put it this way: I have contacts

. My chip isn't a retail version, but an Engineering sample with a downwards unlocked multiplier.
