Hi guys, I tried searching the forums but couldn't seem to find the answer anywhere (I found plenty on the 6850, just couldn't find one specifically for the XPS 8300). I've never overclocked anything before, but was wanting to OC my 6850. I just had a few questions. I'm downloading 3DMark right now to test everything out. I'm a little worried about using the catalyst control center for OC'ing because of the whole warranty thing that pops up (its a new computer with a 3 year warranty, don't want to lose all that just because I click the unlock button). I read that there is that MSI Afterburner program, would using that make it so that if anything went wrong they couldn't detect that I overclocked the card? Since I never clicked the unlock button on catalyst control center? I don't want to push this card THAT hard, I've been reading about some decent sweet spots. Right now it looks like mines at 900 MHz/1050 MHz, was just going to push it to around 950 MHz/1100-1150 MHz. Anyone have any recommendations? Thank you!
