I will be purchasing a new system within the month, and I need some buying advice. This will be a two to three year purchase and needs to meet current needs as well as future needs. I am debating between an iMac and a Macbook Pro. The power-hungery part of me leans toward the iMac, but the mobility hound leans toward the MBP. Regardless of choice, I will have available mobility and/or adequate screen size. I will be purchasing a large screen, if I get the MBP. I will be purchasing an iPad, if I get the iMac. I will be writing film/video scripts, writing essays, and preparing lectures for work about 1/4 the time. I will be using the following programs about 1/4 the time: Premiere Pro (mostly) FCP X (when desired by clients and prepping for teaching editing) After Effects (moderately) Photoshop (frequently) AVID (rarely) MAYA (looking to learn) The remaining 1/2 the time I will be surfing the web and watching TV/Movies. It really comes down to the performance/mobility of each combo. I've listed the theoretical builds below. Thank you for your input. iMac w/iPad air: 27" screen 3.5GHz Quad-core Intel Core i7, Turbo Boost up to 3.9GHz 32GB RAM 256GB Flash Storage GeForce GTX 780M 4GB Macbook Pro w/24" Asus pro monitor: 15" Retina 2.6GHz Quad-core Intel Core i7, Turbo Boost up to 3.8GHz 512GB PCIe-based Flash Storage NVIDIA GeForce GT 750M 2GB <--This worries me the most.
