I believe the card varies between 8 and 8.5 inches depending on the cooler.
Thanks for trying to come up with a close answer for me. I know that the HIS 5770 is 8.37" in length and its a simular card. It has the same open case cooling disign. The sapphire that I bought looks to be exactlly the same, so I'm praying. Anything longer than the HIS 8.37" might not fit because my SATA ports are in the way kinda. Pluss thewre are other 5770's out there in the same open style but come to different messurements like, XFX comes to 8.7" and the sapphire 5770 Vapor that comes to almost 9' This sucks cus the 5770 is the fastest card that will fit my mother board and case, I hope! All because the SATA plugs fall right in line at the end of the MOBO, where the end of the grafics card may be hitting.
