I have a Dell G5 5000 gaming machine, purchased March 1, 2021. According to the user guide, (https://dl.dell.com/topicspdf/g-series-5000-desktop_users-guide_en-us.pdf), page 17, it states:

The following table lists the specifications of the discrete Graphics Processing Unit (GPU) supported by your G5 5000. 

Does this mean that ONLY the listed GPUs can be used in the Dell G5 5000? What I am trying to do is to replace the pre-installed GPU with another one, say Quadro FX 3800 since I don't need to play games on this desktop. If possible, what kind of GPU can be used with the Dell G5 5000? Thanks!
