GTX 960 doesn't support dual ultrawide monitors? What will?

Hi! I am new here, but have lurked for quite some time. I am looking to upgrade my current system. What I would like to get is the ability to use both of my ultrawide monitors. They only have hdmi in. Currently one goes to 2560x1080p while the other will only go to 1920x1080p.

Anyway here are my current specs.
Antec 900 Case (front usbs do not work)
Asus M5A99FX Pro R2.0 6 Gb/s Motherboard
AMD FX-8350 Black 8-Core 4.0 GHz CPU
EVGA GeForce GTX 960 4GB SSC Gaming Graphics Card
G.SKILL Ripjaws X Series 16 GB (2x8GM) RAM
Samsun 850 EVO 500 gig SSD
EVGA SuperNOVA 850 PSU
Disc drive and a upgraded CPU cooler.
Windows 7.

What do I need to get these two monitors running at native resolution (2560x1080p)? Just a new graphics card?

I do some gaming on Steam. Cities Skylines, Euro Truck Simulator 2, Skyrim, etc. Past that it's typical computer use.

I think I would be willing to spend $300-400.

Edit 2: Would this be able to run 2 hdmi only monitors at full 2560x1080p each? ASUS GeForce GTX 1060 STRIX-GTX1060-6G-GAMING 6GB 192-Bit GDDR5 PCI Express 3.0 HDCP Ready Video Card

I don't know if I can post an external link. I can provide it if necessary and allowed.

Anybody? I can't find anything anywhere. I don't want to buy a new graphics card and find out I have the same issue.
