i think I might raise mine to about 75, what do u think this will give me performance wise increase in 3dmark? Also, would this affect it already being overclocked ? Would it allow it to not be overclocked as high and raise temps higher?
it all depends on your card. Some cards will see a large increase while others will see none. I have found that this should be the last step in o/cing your card as it will only give you marginal increases in most cases and if set to high initialy, can actually hinder the o/c. test it and see what it will do for you. I gained 300 points in 3dmark 2001se by upping mine from 66 to 77. but at 80-88 made it difficult to boot and remain stable. I am using a throw away card to test this on so you may want to be more careful than me as most people dont have this ability.
