    My lovely Power Mac G5 Quad 2.5 GHz has done me proud over the last few years and I wanted to see how it was comparing to all these new intel macs using Geekbench.

    I was surprised to see that I scored an insulting 1663 while, I think, everyone else was in the 3000's or more. What's going wrong? I have 7gb RAM and quit as many apps as possible, can I do any more?

    Here's my link:

    Does anyone have an tips for me? is my mac just too old? help me increase it's score?

    Cheers guys

    Restart it, and don't run any apps except for geekbench.

    Hey bart,

    I just created a new, blank user (all apps quitted and nothing running in background) and tried it again on that to no avail,here's my result:

    Edit: You can also compare my results with the other Power Mac G5 Quad 2.5GHz's here:
    My results are all the bottom ones on the far right hand column, this is most disconcerting.

    It turns out that it's my lowest score yet, what do think the problem could be?

    I have the processor prefpane and it shows all four processors going through the motions when the tests are being done... Is this a major problem or something a fresh Leopard install could fix? I'm hoping not, but this may be the answer.

    Might I have not been using my mac to it's full potential?

    I heard that it could be a RAM problem, so I've just done a Rember RAM test, here are the results:

    It certainly took a while and there's also an error in there, could a memory stick not be inserted correctly?
