    Ok, so here is a question. I know my G5 is an aged girl (1.6GHZ) but I dont understand why she plays YouTube videos choppy. I mean my iPhone freaking plays them better.

    The odd part is, that this is really limited to YouTube...Other type video sites, once loaded, no problem so Its not my internet speed, I have a 10MBS line for the house.

    So ill wait for the entire video to load and not even on the HD format of YouTube and after that, you click play and it stutters or the audio will be fine but video will lag.

    As far as computer specs go
    1.6GHZ
    4GB Ram
    Radeon 9600Pro
    10.5.7 (.8 later today lol)

    Any ideas as to why?

    Flash for mac sucks and is slow even on some Intel macs. The reason YouTube works fine on iPhone is it's not using Flash.

    see...I would agree with that but like Vimeo videos, I have really no problem with, maybe slightly slow sometimes. I can download a 1080p video from Yahoo or Apple Trailers or edit in FCP and no problems so this seems to be limited to YouTube...

    hhmm...that might just be it

    It's true, my 1.8ghz PowerMac G5 can barely play YouTube videos either anymore.

    Hell even flash banner ads kill my browsing experience.

    Flash generally sucks on anything not windows. Blame Adobe, they cant seem to get it right for anything *nix based. Flash on linux is horrible, much worse than anything osx has ever seen.

    but has it gotten worse? I swear YouTube and other flash sites used to be fine. Worst offender site besides YouTube is something like IGN.com. Omg does my computer love to explode on that.

    I would blame flash and its updates, in addition to the morons who try and shove everything possible into it for advertisement revenue, rather then the G5. OSX Flash is, as many other people say, not optimised well; combined with bloat/adware, it only makes the overhead worse.

    My G5 eats flash for breakfast, lunch, and dinner, and doesn't break a sweat under Opera/Safari/FireFox; some problems with Stainless (Stainless runs multiple clients AFAIK).

    An interesting experiment would be a downgrade to Flash 9 or summat and then see the differences, if one had the time.

    Time for some tests I think. Random video from youtube:

    CPU usage during HD playback (2008 Mac Pro - 2 x 2.8GHz):

    I'll get the OS X results later. Note: Apple and Microsoft
    calculate total CPU usage differently. For Apple 100% is
    100% of 1 core. For Microsoft it's 100% of all the cores.

    Ok, here are the results of two tests. As you can see, even
    with Quicktime movies (surprise!), Windows is more efficient:

    Notes. Windows 7 includes Quicktime playback support. The CPU
    usage is so low under Windows 7 - often measuring as zero - that
    I suspect GPU-based decoding is being used.

    Here is the movie I used for the second test (854x480):

    Remember: to get the overall use for OS X, one must divide the
    reported CPU usage by the number of cores (in this case 8). CPU
    usage in OS X is measured as a percentage of 1 core (that's why
    it can go above 100%).
