Dell XPS 8300 motherboard and GTX 770 - compatibility issues?

Hello all. I have been planning to upgrade my Dell XPS 8300 with a new power supply, graphics card, and case. At this point, I have not decided to get a new motherboard, and use the one that was inside the 8300. This is the mobo: http://www.findlaptopdriver.com/specs-0y2mrg-dell/


For my graphics card, I have gone with GTX 770. However, after reading online in various places, I have learned that the Dell Bios has compatibility issues with the GTX 680. Some say this problem was patched in a later driver update, but I have not found anything convincing.

However, I have not found any people with 770s having a problem, only people afraid of getting one because of this compatibility issue. My question is, is there anyone who has confirmed they work or don't work? Worst case scenario I can get a new mobo.
