I am in the market for a QX9770. I have been searching for the best price and have noticed several posts on the infamous Ebay for prices ranging from 800-1,500 dollars. Is there some way a person could alter an older chip and make it appear as if it was the correct CPU? Could these be cheap knock-offs or am I just being paranoid. I am not a fan of retail, but I am concerened of being ripped off. I am planning on using a credit card so that I will have some protection.
