Intel Iris Pro for DOTA 2 - 21.5"

Hi imac users,

I would like to ask if does anyone of you have tried playing DOTA 2 in the late 2013 model of the imac, entry level? The one with the intel iris pro graphics?

How's the performance? Can the machine handle it smoothly? At high settings?

Thanks in advance and your answer will help me decide if i will go for this sweet machine

I've never played the game but according to what I've read about the Intel Iris Pro graphics chipset, it's supposed to do well with games. Of course the better 21.5" iMac with the nVidia graphics would be better. I'm assuming you're going to play DOTa 2 using Steam?
