    Finally, many years later than wise, I'm about to upgrade my old G3 iMac... but to which of the new ones - 20-inch 2.0 or 24-inch 2.8?

    As usual, budget is a constraint but, as whatever I buy will likely have to last awhile (I got 7 years from the current G3 - and I'm still happy with it, but it can't handle web video and some other stuff), I'm ok to spend more now to get the smart choice.

    None-too-techy, many of the benchmark tests are over my head. And, although I'll use Photoshop to edit an image for the web, the '21-step processes' used in speed/power testing just confuse me.

    Having maybe a dozen Firefox tabs open, with BBEdit, Thunderbird, Transmit, Photoshop, iTunes and maybe a couple other apps open are about as much as my load gets. Oh yeah, and sometimes I have to open an about-an-hour mp3/aiff and chop it into 5-10 minute bits.

    Realistically, am I likely to get a worthwhile performance boost with the 2.8 rather than the 2.0? Common sense says it should maybe be 40% - but is that likely to be noticeable on my work pattern.

    And, monitor size... I'm getting older and my eyes are crap. I run the G3 15" at 800x600 - at 1024x768 the type is just too small to read comfortably.

    A larger screen should help, but quick math suggests otherwise... with the 20-inch running 1680x1050, that's twice the resolution on a screen just one-third larger - won't that make things even smaller and harder to read?

    With the 24-inch at 1920x1200, that's up to 15% higher resolution on a screen 20% larger - so am I right in thinking 'on a 24-inch, things'll look around 5% larger than they do on a 20-inch'? (And sure, I know I can lower the resolution, but I've noticed things get fuzzy at lower than default.)

    Suggestions appreciated. Please and thanks.

    I think the 20" 2.4 GHZ is the sweet spot in terms of price/power. If you plan on keeping the machine as long as the last one, you probably shouldn't get the 20" 2.0. But I'm not so sure you need to pay the premium to bump all the way up to the 2.8 GHZ either.

    I'd recommend getting the 20" 2.4 Ghz and then buying some 3rd party RAM.

    reward yourself, and your imac hehe

    My old G3's screen died not to long ago, still works with an external crt (but how sexy is that? ewww)

    anyways i would think if you tend to keep your computers for that long, then the smart thing to do would be get the entry level 24".

    you will love the size, and since if you buy apple care it will have to last you 3 years minimum. over the years i see screen size continue to increase in size, 20" is already looking small to me next to my 24" alum beast :)

    i dont think i could use anything smaller than 24"... or maybe the 23" ACD... anything smaller when i use it feels subpar (no to mention when i use my BlackBook in class it looks like a kids toy , haha soooo small)
