Graphics Card Help

Can anyone help me pick out a budget friendly (sub $200) graphics card?

• Doesn't have to be current generation
• I won't be gaming at all on the PC
• Needs to run well on Linux
• Must run 3 monitors
• Biggest workout it will get is streaming security cams on one screen, full screen video on another.
• Power supply is only 295W and I'd rather not upgrade it.

Any help is much appreciated!
