Hey Guys I want to upgrade My Dell Precision m6800 GPU to Quadro P5000.

The First thing That I figured out was that I need a eDP Motherboard Cause The Pascal Family don't support The LVDS Screens .

I found one on ebay can you tell me it is the right model ? :

and also I read in some forums that I have to update VBios to use the Card I found one at the Link below ,please help me if it is the right one and give me link if it is wrong and also I don't know how to update it if is any tutorial . ( does it have that much of risk like updating the bios???)

the VBIOS Link : https://www.techpowerup.com/vgabios/208556/208556

at least I wanted to ask that is there any FHD or 4K Colorful (like Adobe RGB Standard) IPS Panel for my Laptop with eDP.  if there is give me the link and part number if you can.

Thanks a lot.
