But my 2nd RMA card just the **** the bed on me, so honestly, if you can get it RMA'd, do it. Just in case.
The MSI 7950 TF3 I ordered from newegg last week was the same way. The card was louder than any other component in my system. Sounded like a tiny motors cranking out fps. I RMA'd immediately. The Vapor-X I replaced it with is better, but still not as quiet as I would like. I will give this one a few more days then decide. Could my PSU be a contributing factor? I have a PCP&C Silencer 750 that is about 4.5 years old. Probably fine, but something I will experiment with to see.
