    MacPro 4.1
    8 gigs ram
    512 vid card DDR3
    2.8ghz quad core

    I do my color corrections, cue it all up and when I render it, the four cores are at about 25% and read write on my raid 0 set up is 3Mb write and 3Mb read.

    What gives? :(

    okay... maybe the 8 gigs of ram is being all used up... does that have to do with anything?

    oh and 10.5.8 is what I am using

    This is within Apple Color? Color is very GPU dependent. Render times will vary between resolutions, codecs, etc. But the 25% proc usage isn't out of the ordinary.

    Correct me if I am wrong,but I have understood that only the interface,live correction and previews are handled by gpu?
    The final render is done by the cpu´s and the ***** poor performance of those falls down to quicktime/cocoa,they just uses the cores so poorly.
    At least I have not found out any speed increase in rendering when going 7300gt->4870..


    The SL+quicktime X + future FCP might alleviate the issue.

    Color and Motion use the GUI for the preview and the final rendering.

    2 video cards?

    would it help to have two video cards?
    what are optimal cards for this kind of task?

    What do you have now? "512MB GDDR3" isn't a terribly useful description. Also, 2.8Ghz quad core in a Mac Pro 4,1? Do you mean MP3,1? Or 2.66Ghz? I just checked Intel's site to see if there even is a Xeon 3500 at 2.8Ghz, and there isn't.

    FCS doesn't support multiple video cards and it will actually cause problems w/Motion and prevent Color from launching. Color seems to be partial to ATi cards.

    so this is what I have

    this is what I have in my tower:
    http://www.nvidia.com/page/geforce_8800.html

    I'm just curious what better card I could go for to speed up my system/COLOR.
    I haven't moved to 10.6 yet, but from what I understand, having a great video card is going to be great for the whole system. :D

    The 8800GT doesn't perform well w/the Apple ProApps at all. The lower spec'd ATi x1900 XT even out performs it solidly. I'd pick up whatever the current ATi card is that's compatible w/your Mac.

    I want to get around to learning Color but for now Magic Bullet Looks & Colorista are doing the trick quite well. If you're still having trouble with Color give Magic Bullet a shot.

    Ati HD 4870 a good choice?

    Holy crap are there alot of details in gfx cards!!!
    The 4870 seems to be a good choice from what I can tell.
    My budget is 150-250.
    When I am looking at cards, what is the key number to look at as far as color and motion? Pipelines? MHz? Ram?
    And I cannot find a mac compatible list....

    The specs on the cards don't matter as much because it all depends on how well the drivers by Apple are written (hence why the 'slower' X1900 card out performs the 8800GT in Color and Motion). The 4870 is a good choice from what I've read.

    just search amazon for "ati radeon 4870 mac" and you'll find it. however, the 4870 will be outside your budget (it's $350). you may have to go with it's louder/slower younger brother the 3870 which can be had for $220 on macsales.com.

    two part finish up to this:

    1. I actualy had the 9800 gtx+ not the 8800. My bad.

    2. I bit the bullet and got the 4870 and did some tests. IN geekbench, I got a lower score... BUT when I ran a 1.8gig pro res file through color with some basic corrections the 9800 took 48mins, but the 4870 took 24mins.
    Holy crap.

    need I say more?
