So I'm a civil engineering student and next semester I had planned on buying this sweet sexy tablet. I was planning on getting the i3 version because that's more than enough power for my needs and apparently this version doesn't get as hot as the i5/i7 versions from what I've read. But will 64Gb of data suffice? I plan on having AutoCAD and some few other engineering programs installed on it, I'll probably get a micro SD card for media and use OneDrive for general document storage though. Should I splurge on the 128gb i5 version or will that be too much? Oh and I also play some light gaming, no heavy stuff like Destiny or that, just puzzlers and rpg's. So yeah any suggestions?
