I'm plan on a new 15" MBP as soon as it comes out but I need help deciding if I should get dedicated graphics or just use the integrated one. Obviously, it's not released yet so there aren't any benchmarks but let's assume that the new MBP will have graphics that's a generation or two faster than the currently one. I will use the machine for primarily for software dev, running multiple VMs and app servers. No games, video editing or photoshop. It will also be driving a 27" 1440p display. Since I don't do any photo/video editing or games, integrated graphics should be good enough but I'm worried about long term capability. I intend on using this computer for the next 6-8 years so would dedicated graphics be better long term? Especially as 4k monitors become more common?
