It is x16 and Im stress testing my computer and right now, it is still running and 30 minute have passed. It crashed my computer during game and during stress test few hours ago but it seems fine right now. My comp is being so random. It will probably crash again sometimes.
I had the same problem with my old HD5770, it turned out my card was defective. If it's still under warranty you may want to RMA it ;P
