Well I originally bought 2 BFG 7900gtx and both static bags had been resealed, so I felt for that kind of money they should be brand spankin new, so I returned them and of course at the time they were out of stock. So, I bought 2 BFG 7900 gts and both circuit boards have a component that fell off and they're rolling around inside the clam shell on top of the board in the sealed box!! I called BFG and they said I was not the only one to report this issue...so check closely before you leave the store.
