Yea, but before you do that, test that the card can handle it. I can make it whatever speed you want.
You can still have a 7950 BIOS with speeds of say 550/675 if that is all your card can take.
Definately check out my GuruOfGaming link for the heat mods.
It would probably be better if you sent me your BIOS and you just clocked it up instead of going with the 7950 BIOS IMHO.
Sweet deal. Re-Check the 7950 GTX topic on the GuruOfGaming forum because I am on heatsink mod ver 3 right now and I have learned A LOT about the cooling problems waiting to happen on this card with the stock heatsink.
