I'm a photojournalism student working with Final Cut Pro and Photoshop. I've been using the desktops at school, but now I have a new baby and need to do all my editing at home. I'm having a hard time deciphering the jargon around the specs, especially concerning graphics processing. It looks to me like the integrated Iris graphics cards are not that great for video work (do you agree?) but I can't figure out what to get instead. I want this computer to last into my professional life, and it needs to be a laptop so that I can tote it around the house and watch the baby. I'd be grateful for any specific suggestions or opinions as to what specs I need. Please define any acronyms or jargon! Many thanks.
If you're looking at Intel Iris, I'm guessing you're looking at the 13" Retina. Mind you, the 13" Retina is not at all a bad machine and for light Final Cut Pro tasks, it'll probably be passable. That being said, if you're planning on doing more than just light tasks, I'd go for a 15" MacBook Pro. Your options there are Iris Pro or Iris Pro AND a discrete NVIDIA mobile graphics processor. Iris Pro is pretty formidable; equivalent to the discrete mobile graphics of three years ago if not better. You do get future proofing benefits by getting Iris Pro and the NVIDIA graphics.
Either way, unless you're getting the non-retina 13" MacBook Pro for some reason (and, while it's a fantastic machine, I don't recommend getting it at this point in time), you NEED to max out your RAM and your storage AT THE TIME OF PURCHASE (you CANNOT do this later).
That said, so you can learn a little jargon: When it comes to graphics, there's the model name (Intel Iris Pro, or NVIDIA GeForce GT 750M for example) and really if there's a numerical, assume that the first digit is the series, and the second digit is how good it is in that series (Intel stuff works a bit differently). For NVIDIA, GTS > GT > GTX. Otherwise the spec that matters most consumer-side is the amount of video memory each has. For Intel Iris and Intel Iris Pro, the graphics uses the system RAM. The NVIDIA GeForce GT 750M has its own RAM dedicated to video processing, which makes graphics render faster. That said, graphics that share RAM with the system ARE catching up, but you'll still get better performance from something with discrete memory. With MacBook Pros that have these more powerful graphics options in tow, you get both the integrated graphics (Iris Pro) and the discrete graphics (NVIDIA GeForce GT 750M) and your computer will automatically switch between the two depending on the task at hand.
