What water-setting do you have and what other settings in the ini-files? Are you sure you run the game with 32 bit color-depth? It would help us to determine what the problem is, if you post your settings listed under "[Render_OpenGL]" from your conf.ini-file.

If somebody has the same card you have, but no such problems, it's likely your settings rather than the drivers.

Besides that: Did you deinstall and reinstall drivers after switching your cards?

Just learnt a tweak to control the idle temps, heard it's toasty on the stock units.

If you make a profile in catalyst after turning on Overdrive( make sure clock and memory settings are correct). You can then go to the file "C:\Users\your computer name\AppData\Local\ATI\ACE\your computer name. XML. the xml file will have the same name as the catalyst profile you saved. right click and hit edit.

<Feature name="FanSpeedAlgorithm_0">
<Property name="FanSpeedAlgorithm" value="Manual" />
</Feature>
<Feature name="FanSpeedRPMTarget_0">
<Property name="Want" value="0" />
</Feature>
<Feature name="FanSpeedPercentTarget_0">
<Property name="Want" value="65" />

Change the value to "manual" and Want value to "65" (% of fan speed)

Save the file then reload your profile in catalyst.

For fellow XP'ers it's under C:\Documents and Settings\"your computer name"\Local Settings\Application Data\ATI\ACE\Profiles.xml

Knocked 10 degrees off idle and 5 off load on here.
