That all depends on your current monitor, if you get a high end offering that has a native resolution of 1920x1200 with AF x16, AA x16 (+ any other settings or post processing) then you may hear those 9600s cry.
On the brightside thats where the 1KW PSU comes in handy (assuming u are able to grab a high end multi-gpu config).
