your current 3dmark score should be well enough for mostly anything!!! (well unless you count hardcore games like farcry... but you should still be able to run that pretty well). You could o/c your video card. Last i checked the program to use (well tye program i used on my 9600 rp like half a year ago anyway) was radclocker... it allows you to o/c both your core and your memory. To o/c your video card simply download the program, then scale both the clock speed, and the memory higher... run 3dmark 03.. until you see some sort of anamoly, or the picture goes bad keep upping the core and mem....
