I been reading many reviews on the Intel Quad Q6600. Most if not all of them say that there are two different types of Q6600. B3 and G0 versions. B3 I think was the first iterations possibly and the latter the latest made. I just bought a bundle from Frys Electronics. I want to make sure I have the G0 version before I open the box. Is there any possible way to tell which of the two CPU's I have by a serial number or something? Thanks in advance. Laterz.
