    so I was curious if anyone has seen any stats on an iMac gpu with 256 over 128...? isnt significant or not? I am curious because I have an iMac 20" intel duo 2.0 w/ 2gig...
    any programs to check the clock speeds as well?

    Same here, I plan to get an iMac 20" and run it with a dell 2005FPW.

    With dual monitors I think it would be better to have the 256mb VRAM, but I'm really not sure about the clock speeds, I'm assuming they'd be the same though.

    you could check the clock speeds with ATItools 0.25 beta.
    it only works under XP

    so whats the advantage of 256 over 128mb on a video graphics card if it wouldnt make a difference ?

    well the #1 difference is that if you run two displays the vRAM for each display on the 256MB card would be 128MB while on the 128MB card it would be 64MB per.

    So you have more vRAM per monitor.

    That and the UI seems smoother when you use expose, dashboard, etc..

    I read a post earlier, basically the UI is stored in vram so that it can easily be manipulated when you activate expose, dashbaord etc

    The only difference between the Radeon X1600 256MB and 128MB versions is the size of the VRAM- I think that they both have the same clock speed. :)

    I could be wrong though.... :eek:

    The biggest difference is in whether or not you play 3D games.
