yeah the nvidia software can let you change ur clock settings, but do it with caution...luckily the software also has a test button so u can check it before you set it so the chances of screwin it up are a lil less...my card came 450mhz core and 1320mhz for memory clock from factory i got it up to 495 core speed and 1400 for the memory...i need to get a better heatsink before i go much higher with it though, but as it is it runs about 64 degrees celsius under bout 4 hours of hard gaming.
i have yet to try it yet but i heard bout a program from the site below that you can unlock the pipelines easier and stuff
