I just purchased a computer from viciouspc.com and I got a 9700 pro board with it. I know it is a pro becuase I took it out and it said "sapphire 9700 pro" on it. However, the core/mem speeds come stock at 297/290 which is not right, pro 9700s should be 325/310. I know it's not a 9700 np becuase np's are 270/275. when I overclock it to what the speed should be (325/310), I get minor artifacts. This should not happen with a 9700 pro at stock speeds. I was hoping to get it to like 350/325 or something to that effect. What could be wrong with the card?
