Going to do an upgrade soon, and am unsure if one is any better over the other. From what I've gathered, AMD is typically better for gaming and P4 for hard number crunching. But, is there really much difference? I was thinking about the AMD64 in the 3000+ range or the P4 in a 3.2GHz range. One thing about the AMD64 is it is ready to go for Windows 64, but is that of any real value? Comments are appreciated. BTW, I will be doing the upgrade myself.
