That is dependent on a lot of variables. The question is what are you going to use your GPU for. Is this a workstation? Is this for gaming? Is this for compute? Or maybe video editing? What is your budget? Are you willing to also buy a new power supply if needed for the GPU?
Basically any GPU should work assuming you have the power to drive it.
Many Professional Video Editing software recommends Professional GPU models.
As an example only Adobe Premiere Pro: Adobe Premiere Pro System Requirements
But with most Video Editing software you can use Consumer GPUs as long as it meets the minimum GPU requirements even with Premiere Pro. The above is the RECOMMENDED GPUs for that specific Video editing software.
Worth noting while most of the software packages support cards from both Red and Green teams many of the plugins do not. So make sure to not only pick a GPU based on the software but any plugins to that software you already or think you will use.
