    You have to disable PowerPlay for HD3870 / 3850, it is not so easy to do.
    How to properly set your card up to not use powerplay which causes
    stuttering and low performance.


    Go to the directory,
    (Windows XP) C:\Documents and Settings\Administrator\Local
    Settings\Application Data\ATI\ACE
    or
    (VISTA) C:\Users\Administrator\AppData\Local\ATI\ACE

    Keep that directory open.
    Start up catalyst control center.
    Hit the Overdrive tab.
    Hit the paddle lock image to enable the overdrive settings.
    Hit the profiles tab at top of page.
    Select profiles manager from drop down list.
    Name a profile in blank box (FixPlay is my chosen name), under "this profile
    includes" section at bottom of page select the dot for "the following
    settings". (In the tree make sure only ATI Overdrive checkbox is selected.)
    Hit the save button.
    Hit the Activate and close button at bottom of page.

    Now go to your open directory
    Go to the directory,
    (Windows XP) C:\Documents and Settings\Administrator\Local
    Settings\Application Data\ATI\ACE
    or
    (VISTA) C:\Users\Administrator\AppData\Local\ATI\ACE

    You should see 5 new files in there in total.
    One file is the same as you named your custom profile, right click it and
    select edit (my file is called FixPlay.xml)

    The file will open in notepad where you can now change settings to nullify
    powerplay.

    Here are my new settings for example, I have increased the core speed to
    776Mhz (from defaults 300MHz) and voltage to 1,300V in 2D mode, and applied
    a overclock to the 3D modes for the GPU (852MHz, increased the voltage to
    1,315V) and for the memory (1200MHz). I also increased the fan % to 100%
    from 41%.
    Please, be careful with increasing the voltage it may damage your GPU, also
    note that high overclock may lead to overheating and damaging your card
    permanently!!!

    </Feature>
    <Feature name="FanSpeedPercentTarget_0">
    <Property name="Want" value="100" />
    </Feature>

    Make your changes, close and save changes to the file.
    Right click the file choose properties and change the file to read only. You
    are done.

    If you restart your computer, just make sure to open catalyst and ensure
    that your profile is activated. Simple once done.
