Graphics cards compatible with Asus P5KPL-CM

[evanc123_]

Hello,
I have a computer that I built with an Asus P5KPL-CM motherboard, Intel Core 2 Duo 2.8GHz CPU, and 4GB of DDR2 RAM running Ubuntu 16.04.

What graphics card would you recommend buying for watching videos & movies and light gaming with games such as Team Fortress 2 and Unturned.

Thank you!
