$500 GPUs where the end product being developed is a dot com; isn't that excessive?
Yeah, an APU is plenty for most development tasks, specially for web development.
I don't fully understand the 5k monitor. Is the difference noticeable? I find anything over 'retina' to be unnoticeable, but maybe with a 30 inch monitor it's different
It gives you more real estate on your monitor.
It says in the article that the tag engine runs on GPUs so there's a need for a fast CUDA processor during dev. Also, Intel integrated graphics drivers are still a pain and have issues with some displays.
I totally understand the setup, but when I hear 64Gig of Memory, I always eager to get ECC memory.
That's why I would have chosen an AMD cpu with a mainboard which allows ECC memory.
