    I havent paid that much attention to the comparisons as they tend to be
    very windows based and games to boot. But surely its hard to compare
    across platforms. The CPUs require different chipsets, so some of the
    performance results can be due to the MB and RAM.

    The P4 640 3.2Ghz is about the same price at one of my suppliers as the 64
    3500+ and the numbers are not that different.

    For me to switch to a different platform and risk stability issues there
    would have to be some decent payoff in either cost savings or serious
    performance differences. I am thinking perhaps for my RADIUS accounting
    database which is very large might benefit as I have already maxed out the RAM.

    Nahhh... I am an uncool kind of guy. Hell, my glasses are still from the 80s!
