What would be some good graphics card choices for this older build?

Someone gave my little brother a custom built PC with these stats:

Motherboard: Asus M4N68T-M V2
• CPU: AMD Athlon II X2 260, 3.2 Ghz
• RAM: DDR3 8GB (2x 4GB sticks)
• Hard Drive: Seagate 1.5 Terabyte HDD
• Power Supply: ATX TL500w BK 12V
• OS: Windows 10 Home
• Optical: Lightscribe CD/DVD burner
• Case: Cooler Master

I'd like to buy a used graphics card (under $50) for this build, but I'm not sure what this would support?

Thanks!
