As mentioned, the RX 460 and GTX 1050 are possibilities. For grins, here's pcpartpicker's look
at the two models.
Newegg is running a rebate on the Gigabyte Windforce RX 460. So, $90 after MIR, or $120 w/o rebate. The windforce does have a passive fan for 2D and light 3D loads and 1 displayport output. I don't like that it doesn't have a PEG power connector...but again I don't know what your applications are and if they will drive the gfx cards like a game. Otherwise, reviews look good - viewtopic.php?f=19&t=69366
For $130, there's a bunch of un-reviewed but likely decent GTX 1050's.
Or, spinning this thing on it's head, what if it's just time to replace the CPU/mobo and get something modern with displayport on it and avoid the discrete gfx?
