Video card suggestion for HP ML110 Gen9

[FGN]

I own a HPE GEN9 ML110 server, such as Windows Server 2012 R2 installed serving Hypervisor function with Hyper-v and I have two virtual machines running. I need to provide more powerful graphics capabilities to these virtual machines so I need to install a video card that server. I need to find an alternative benefit cost for the plates that are approved by HPE to me and unfeasible cost because the value is up to 3 times the server.

those thought are these:

HP NVIDIA Quadro K2200 Graphics Accelerator J0G89A
HP NVIDIA Quadro K4200 Graphics Accelerator J0G90A

Does anyone have a better suggestion?
