Will I have enough processing power?

[iMore Question]

I am looking to purchase the $1,999 15" MacBook Pro with Retina Display. My question is in regards to it's processing power. The specs I'm interested in for it are as follows:

2.2 GHz quad-core Intel Core i7
Turbo Boost up to 3.4 GHz
16GB 1600MHz memory
Intel Iris Pro Graphics

I'm looking to do video editing, music production and graphic design such as Photoshop on this computer. What's also important is I want to be able to edit 4k footage on this computer which I understand can be taxing if there isn't enough processing power. Would this computer be able to comfortably handle processing these programs or should I look at purchasing a 13" quad-core Intel Core i7 with 3.1 GHz for $200 more (Not listed on the Apple website but is in their retail store). Thank you for your input.

I don't think they make a quad core 13", it's a dual core.

Stay with 15"
You didn't mention video memory.
Get 2gb video memory
SSD drive is also great
