So first off hello to everyone, new here and new to macs, but not new to apple. My windows 7 pc is starting to go after 2.5 years and while I loved the machine I can't have an unreliable computer as I am a merchant marine and at sea during the summer and go to school during the year. For the reliability of macs I am willing to make the jump from windows and dive into this new world, but I need some guidance. My w7 pc was an i7 quad core forst generation at 1.7 ghz with 8 gigs of ram and a dedicated graphics card. I used the crap out of this thing and it got really hot, and I think that's what caused the problems it is having, after smelling some burning. So with that in mind I am in the market for a new laptop and not sure what to go with. Obviously I want the new retina but not sure if I want to go with the base model or the 2.6. Or of I should stick with the old style. I will be running photoshop, Lightroom, autocad, video editing software, and some other big programs. Most of the time I run them together or in different combinations, all which the 1.7 was able to Handel decently. So what do you guys think would be the logical computer to go for based on the programs I use and the laptop I am coming from? And I have no problem using safari so as long as the internet looks good in that on the retina I have no problem. I don't need to run chrome or Firefox. Thank you for any help!!
