I've seen many posts regarding problems with XFX so it seems they just don't know how to make good cards.
The XFX are buggier cards, expisally the first batch. The first batch of all the 6600GT's wasnt good, and XFX got hit hard by using slightly cheaper parts, not always remebering heatsink clips and bad nvidia cores.
Just RMA it and get yourself a new card. Besides the fact that XFX has had quality control issues, their a good company.
They also offer faster memory than the trusted EVGA.
