New PC desktop - need monitor advice

Okay, I finally broke down and bought a new desktop. See it here

Now I need video help.

My current system has an Nvidia GTX550ti. It has a DVI output (which variety, I'm not quite sure) and a VGA output.

I have a 20" AOC monitor with a VGA input only. It connects to the card with a DVI-VGA adapter. The 2nd monitor is a crappy old Acer 19" 4:3 that connects to the VGA port on the card.

So what I want/need to do is make the AOC 20" my secondary monitor, toss the old Acer, and buy a new 24 or 27" monitor for my main display. I need help.

The Lenovo has a video card in it. AMD R9 255, so they say. It has 3 connectors:

DVI-I Dual Link

HDMI

Display Port

So here's what I think I can and want to do. Please tell me if it's possible and/or makes sense.

a} use my existing DVI-VGA adapter on the card's DVI-I port with my existing AOC 20" VGA monitor as a 2nd display, and

b} Buy a 24 or 27" monitor with a HDMI input, and the associated cable (HDMI-HDMI) for a main display, and

c} ignore the Display Port connector.

Am I on the right path? I love how smart my friends are!

Yes, but the displayport connector is very cool and I would pick one over HDMI given the choice.

Teach me why, please. What special magic is in this port?

Basically more bandwidth. They can run a 4K display at 60Hz, where HDMI is limited to 30Hz. They also work with a variety of adapters to convert to VGA, DVI, etc.

If you're getting a 1080p screen it doesn't really matter though.
