So here's the deal. I trade in the market on a daily basis and have TWO 27" monitors attached to my brand new 13" rMBP w/ 2.4ghz/8gb/256gb. The monitors are simple 1920:1080 dell professional series monitor (P27xxx). I want to add a 3rd 2x" monitor to the setup. The problem is, I would need a box by Matrox called the triple head to run all 3 monitors from my macbook. This device is $300. My other option is to return my rMBP and buy a 27" iMac. I have an iPad that can do much of what I need on the road, however I will probably end up with a macbook air at sometime. This way the iMac will give me the real-estate I need on my screen and can adequately power both monitors. I am at a loss at what I should do. I feel like I am asking my rMBP to do to much. please with it 2 1/2 feet away and lifted on the twelve south hi rise stand, the screen isn't the easiest to see. What do you guys suggest?
