How far can I expect to be able to push the 6950? And to my knowledge (by me looking) I don't have a bios switch. So do I have any options there and should I even bother trying to go nuts with this card or just try to sell it for decent price online and buy one that has a bios switch or better clocking abilities. I have MSI afterburner unlocked to where you can change the voltage etc. I don't know, just give me your input I'm all ears. Appreciate it guys.
