Hi, Being a Microsoft .NET developer I don't really have to think of what OS to use mainly but still my last 3 Notebooks have been MacBook Pros running Windows, simply because there just wasn't any real alternative. This year though I decided to get a "real PC" but 4 PC laptops later I've yet again came to the conclusion that the best PC laptop is a MacBook Pro 15" 2015. Normally, I would just get a version with everything maxed out no matter costs but this year I'm having some doubts, mainly with the choice of GPU (Graphics card). IF GPU Switching had worked fine under Windows it would have been a no brainer but as most of you probably know it doesn't. Which have me thinking of if I should get the one without the AMD GPU instead to get better battery times and would like to hear your opinions on skipping the AMD version if favor of just the non AMD version. This will be used mainly as a mobile workstation so I don't really plan to do any gaming on it, most GPU intensive stuff will probably be some movies and light Photoshopping. Now, a few questions: Whats you overall opinion on skipping the AMD version for my needs and just go with the non-AMD (Intel Iris Pro version)? What are the chances currently of getting a Windows installation that supports GPU switching? I know there are different "hacks" out there that is supposed to solve this, but it still seems kind of shaky (no offence to the developers)? I noticed there is a "GPU swtiching utility" available on GitHub (could have been CodePlex also) that is said to be able to support GPU switching even though it would require a restart each time. That would be fine by me if it worked. Anyone that have used that one (or would consider trying) and that can give on opinion of how well it works? Will the built in Intel Iris Pro GPU be able to handle an external 4K monitor with no problem (just office use and some movies) over mini-DisplayPort or HDMI? What are the chances that the upcoming Windows 10 will offer better support for GPU switching on Macs running Windows without the need for "hacks"? Anyone tried it using the preview versions? Feel free to comment on anything related that I should have asked for/mentioned but haven't Thank you.
