is this a good score increase??

[bushwickbill]

At stock speeds I get 9329 on 3DMark06, At max speeds, 648/1620/900 I get 9895. (roughly 550 point increase) Is that a good score increase for my card. My Cpu is only slightly oc'd for testing. Now that I have found my new max speeds i will re max my cpu to get a new high score on 3DMark06. What else is there for a accurate GPU test that gives you a definitive result not just avg's?? Aquamark is good, what is there anything else out there that I can use? And what are some of your score increase's for GPU overclocking alone? Thanx people.
