    There were some Photoshop benchmark tests from macaddict.com that showed that the dual 2ghz with with 2gigs of ram MAKES A HUGE DIFFERENCE. They ran tests with and without the extra ram and the differences was huge.

    I think in one test its was 20 times faster than dual 1ghz with 256 megs of ram. Too bad they didn't put 2 gigs of ram in all the other machines they tested.



    Apple should be shipping these machines with 1 gig of ram at least. Not a meg less.

    I response to the CPU usage with moving windows I have tested this on a 3 PCs.



    AMD 1800 768M Ram Win2k

    AMD 2500+ Barton 1G Ram Win2k

    P4 3.0 1G RAm Win XP Pro



    ALL USE 100% CPU when moving windows. Also All of them take a VERY long time to open MS System Info (comparable to ASP).

    No they should have 512 on the bottom. I mean come on, let's go to DealRam. $79 for a stick of 512. No excuse to not include. Apple of course would charge you hundreds of dollars. This RAM thing is getting old fast. I know they like to squeeze money but this isn't the right place to do it! It really affects speed when you page out!

    Does iTunes resize smoothly on a G5 while doing average stuff (AIM open, iTunes playing, Safari loading something, and the other odd app going?

    This guy should try launching Mozilla, Visual studio, and Visual sourcesafe on the PC sometime.



    Question: how many apps were in memory at the time he decided to launch four more? It isn't as if people tidy up after they play with a machine.



    Either way, comp USA should be shot for having a demo machine with only 256 MB of RAM.

    While Apple's RAM is unconscionably expensive, there are many quality levels of RAM and that which sells for $79 for 512 absolutely is not coming anywhere near my computer.

    Nope. First launch, right after initial startup.

    but if they have a machine there with 2 gig o ram, then your not using the machine that you would take home for the price marked on the card next to it..

    Interesting. On my little ol' 900 Mhz G3, I ran a few rezizing tests. One with an 11 item window, one with a 60+ item window, and one with a 9 item HD window. In all cases the CPU monitor went up high, but performance was fair to good. And that's on a machine with 256MB RAM and not even a 1Ghz processor.

    Launches 4 apps at once. Does Windows even let you do that? I don't think so. And Apple doesn't help by stocking 'em with 256MB RAM. They should have at LEAST 512MB (768MB or 640MB on 1.8Ghz)

    iTunes has a ton of stuff going on inside of it. I imagine that the G5 doesn't have much of a problem resizing. I think the G4 has trouble with iTunes cause of the slow bus.



    I noticed that many common functions in the OS were no faster on the G5. Apps opened a little faster, but over all I think OS 10.2.6 will not run much faster than what maybe a 1Ghz G4 will run it at. 10.3 will probably be faster. But anything over 1ghz G4 is about as fast as you need to get full performance out of OS X. I am betting panther will allow all computers to run the OS X better especially the G5.

    that would be 10.2.7 on the G5 I think. From what people have said panther is faster than jag on every machine, and I think it will kick ass on the G5.
