Open box.They had a bunch of different 780's hovering around $390-450, due to people buying them at $600+ only to find out nvidia just lowered the prices. Mine wasn't even opened or taken out of the case. I also saw an EVGA 670 for $139, and other great deals. Best store ever. The thing is, I just sold my EVGA 780 a month ago for $620, which I also bought at Microcenter for $550 (open box). Here is a pic.
