    For graphics work, which one?

    Let's just say they have the same ram, graphics card, etc.

    Single 1.25gHz, hands down.

    If you are going with Apple's specs, the dual 450 has:

    Bus Speed: 100 Mhz
    Data Path: 64 bit
    RAM Type: PC100
    Mininum RAM Speed: 133 Mhz
    Maximum RAM: 2 GB

    Level 1 Cache: 32 k data, 32k instruction
    Level 2 Cache: 1 MB backside, 1:2
    Video Card: ATI RAGE 128 Pro
    VRAM: 16 MB

    ==========================
    Whereas the 1.25 has:

    Bus Speed: 166 Mhz
    Data Path: 64 bit
    ROM: 1 MB ROM + 3 MB toolbox ROM loaded into RAM
    RAM Type: PC2700 DDR
    Mininum RAM Speed: 333 Mhz

    Level 1 Cache: 32 k data, 32k instruction
    Level 2 Cache: 256 kb on-chip, 1:1
    Level 3 Cache: 1 MB DDR SDRAM per-processor, 1:4 (2 MB for 2x 1.25 Ghz)
    Video Card: ATI Radeon 9000 Pro
    VRAM: 64 MB
    ==========================

    Thats a significant difference, and not just because of the processor. FSB and type of ram is very important. Besides, I dont think the 450 and the 1.25 CAN have the same video card, and I know it cant take the same type of ram. The single 1.25 is a better choice, not just because of the processor speed, but the architecture of the box as well.

    Dont forget, a dual machine doesnt mean it runs twice as FAST, it can just do threaded tasks simultaneously.

    The difference, in essence, is this:

    I've got a dual-450 MHz G4 on my desk.

    I WISH I had a 1.25 GHz G4 on my desk, even a single-processor model.

    'Nuff said?

    the duals are going pretty good on ebay right now... (as in 600+ for the machine) (more or less, depending on config), so that would take a nice chunk out of the cost of a new machine.

    the video card alone would make a nice difference - the actual proc speed from what i've heard (from others who have made similar switches) doesn't make too big of a difference, but X does love its vid ram... and it would run panther pretty sweet... :)

    oh, and if you decide on that 1.25, and you just feel like getting rid of that 2 x 450, *cough* give me a call :)
