Thanks for your Answer!
The Graphic card in the Picture is not the Graphic card that I destroyed, I used it just for better Identifikation. I already soldered off the capacitor you are meaning, since i had the same Idea, and measured it. The multimeter said 23 pF and I also figured out that the sice of the missing capacitor is propably 0603 (imperial-smd-code). I then downloaded the schematic of the card to see if there are different values to this form factor and there are (4.7uf, 22uf...). Thats why I am not sure which capacitor to install and asked for help.
