Did you try the new drivers posted on this site a few weeks ago? Supposedly they fix the flickering problem.

Main reason being it flickers while i'm playing swg and its irritating the **** outa me. From a FX5800 to ATI 9600Pro, considered a upgrade? or downgrade what say u.
In terms of speed FX5800 wins hands down. But pic quailty and soon to be popular HL2, i think ATI has the edge.
