Gpu in optiplex 390?

[Bondoville]

Does anyone know of a graphics card that will work in a optiplex 390 that will play fortnite?

 

I know it may be a long shot but my son is into fortnite and the computer he has set up to play some of his games is an optiplex 390 it has a i5 2400 and 8gb of ram. I don't want to have to upgrade the whole thing just for him to play fortnite. If he wants to play other games in the future I'll worry about it then. Thanks everyone for any help you have!

Thank you so much. My son appreciates you as much as I do haha. He's been stuck playing fortnite on the switch and can't wait to use a keyboard and mouse!
