"At the time of purchase, I was aware of the FX5600 revision and inquired as to the revision of the card / GPU, stating that the newer GPU was much faster and I didnít want to be stuck with the old one. They told me that there was only one revision of this card, and that they had just got them in. "Foolado" me, decided to take a chance and order it. Unfortunately, they were wrong and when the card arrived it turned out to be the older 5600U core. In fact it turns out there are 2 versions of the Gainward 760XP and the newer one does have the 5600U core, and a Firewire card is bundled with it also. "
