MacBook – MBP 2015 with Iris Pro Only and External Monitor

displaygpumacbook pro

I'm about to buy a MBP edition 2015 (15'').

There are two models:

  • model having only Intel Iris Pro (without dedicated graphic card)
  • model having Radeon graphic card

I don't play video games, and I do not use 3D/video softwares.
Mostly programming softwares.

However, I want to use an Apple Thunderbolt screen of 27'' as external and additional monitor.

Should the model having only Iris Pro be enough to handle this monitor (multiple-displays)?
