Hey Guys, I'll be buying an updated MBP 15 whenever it's refreshed. I'm coming from an older 13 inch and the extra oomph for my Xcode projects would be nice. The catch is I already am not going to love the weight gain, and the heat gain on the 15. I have a pretty beefy Windows machine for gaming, so I am wondering how much of a difference in battery/heat I would notice if I chose a MBP 15 without the dGPU. I'd still be upping the CPU from base to a higher model in either case. Also, I will be getting an external display at some point around the same time and if I go without a dGPU, I'd like to make sure I could still drive the display. Thanks!
