Besides what you see on net, anybody here tried this game on their own SB? I have a SP4, I didn't think this would bother me so much as I wouldn't use SP4 for gaming all that much, but seeing how this one game will just crash to desktop without an error, I'm pretty sure it's an issue with the IRIS 540 not having updated drivers to run it. So now I'm wondering if I should get the SB? being almost $1k more for a similar model (SP4-i7/16GB/256SSD) SB would be a i7/16GB/512SSD, no 256SSD version with 16GB RAM. I guess I could go with 8GB ram w/256SSD, that's only ~$300 difference. Probably less when I minus the Type cover. So.. if games run without crashes (granted, frame rate will be low on newest games) on the dGPU: To get Surface Book- Pro: 1) dGPU- games will run 2) bigger screen 3) battery life (web browsing, not gaming) will be closer to the 9hr w/keyboard. The SP4 is closer to 4-5hrs. Con: 1) Price 2) Overall size- It's bigger. But not sure how that will effect everyday use. 3) Weight. SP4 is under 2.5lbs. The SB will be almost a pound more. Now it's getting on the medium weight for notebooks of this size. Gaming notebooks is about 4.5-6lbs of this screen size. 4) No kickstand (not often do I have the SP4 without the keyboard, so same line of thinking, the SB would have the keyboard and offset not having the stand. But when I do use it without keyboard, I pop-out the stand to help hold the tablet. 5) Larger power brick. But supports way more power output.
