Precision 7680 & Precision 7780 Owner's Thread

[GPU upgrade]

Hi, I'm new to this. Looking to upgrade a 7680 with only the built-in GPU with a dedicated one, pref. the RTX2000 ada 8gb. I know I need a different heat sink assembly, two 80p bridges and a power cord. What are the compatibility issues between 7680 and 7780 cards?

7680 cards and 7780 cards are physically different sizes & layouts. You can't mix and match them.

 

[Edit] I was looking at eBay and I see that some listings for a RTX 2000 show compatibility with both 7680 and 7780, so I thought maybe I was wrong (about lower-end cards at least). But then I noticed they ask you to pick between 7680 and 7780 with a drop-down. It still looks to me like the cards can't be swapped between systems.
