Need an advice on setup/mac pro

Hey everyone,

Being a long time reader of these forums, this is my first post.

Having just sold my whole computer setup that was outdated, I need to get a new one.

I almost made up my mind, but I would like the opinion of others on this simply to compare.

I have around a 4-5k budget to get myself a whole new setup.

Being a student, an avid gamer and also doing a lot of video editing and processing,graphic work professionally, I was wondering what would be the best option for me.

I am was thinking into buying a 13 inch mba for all my work on the go as I travel a lot during the week and a new Mac Pro if they update it soon as my main workstation on which i could dump all the more intense tasks.

That being said I also considered the iMac, but the graphics card in there is a mobile version and I think that I could really benefit from the better processor of the mac pro.

What is your take on this?

Thank you for your advice!
