I love how the spirit of the title got mistook about three different ways.
It's also interesting to see some B3 owners bashing the G0 like "hah, see it only does another 100mhz, I feel much better". It's not like if you got a B3 your dong is smaller than those who got G0s. It's just an incremental stepping, happens all the time. We can't always hold out for the best, cuz then two weeks later there's another best. You made a purchase that at the time was just fine. No worries, nothing wrong with it. Should we all dump our 72" 1080i displays because there is now 1080p and content for it? Um, no. Your wang will not shrink, trust me.
And folks, that's 100mhz on the high end... there's a couple more benefits than just "zomg how hard can I rockz this chip with my $300 aftermarket cooling rig". Yeah it's fun to push the upper limit sometimes but that's not the ONLY reason someone might buy the G0.
I personally desire a G0 because I can moderately overclock and not have to worry as much about temps. It's easier to get a G0 to 3ghz than it is a B3. Not much, but still a bit easier. Not to mention the heat and energy savings, little that they may be. It's like which version of a program do you want to download... ver. 1.0 or ver. 1.04? 1.04 probably has some improvements over the original release. Yeah, think I'll take version 1.04.
Just my thoughts.
