G0's are marginally better from what I've seen but it's not outstandingly better than B3's. I'm with you - why pay the same for even a little bit less. And also - I haven't tried to run stable at 3.6ghz. I'm pretty sure others are stable there (of course their temps were higher than what is probably wise). I'm very stable at mine but I think I could reach 3.4.
too bad you didn't have the P35 DS3R, then you could teach me to overclock
