what clock on your cpu? Download fraps to see how many fps you're getting. Also, disable/un-check "Catalyst A.I. -- Enable Surface Format Quality" in the CCC. If there's still no improvement, try setting the game to the lowest settings and run it. Then start increasing the settings little by little until you notice the lag during game play. .

Try bumping up to 3.6-3.8 and if it allows, 4.0-4.2. You get a noticeable boost in performance.

correct. OP run MSAA at 2x. Because MSAA 4X requires more than 1 GB. If it still stutters just run with MSAA turned off.
