What video card can I put in a Dell Precision 380 that will work with Windows 10? It has an Nvidea Quadro FX 3450 card now.

I need help! So I'm reaching out to you even know this is not the forum--any ideas? Loved to make this ol' 64 bit run again for my kid!

I need to get a video card that will work with Windows 10 on a Dell Precision 380--It's a PCIe card with a power connector on the card. Can't figure that out. Any ideas? It has a FX 3450 card now.

Also I have a Pentium D 3.0 GHz with 8 GB of RAM so it's working--kind'a. I can't update the driver on the video card because this is so old, but it's running Windows 10 without a hiccup except for the video latency--skips like crazy--Didn't have the problem with XP: just after the upgrade. Mind you, this is 64 bit
