Is it worth upgrading the m3 to i5 on the low-tier model (256 GB SSD)? Adds an extra $100 to its base price. Will be using computer for general browsing, web development (without VMs or at most only 1 VM) and hopefully some light gaming. Figured I won't need 16 GB RAM for only 1 occasional VM and 8 GB is more than enough for browsing with Safari, even when having lots of tabs open. 256 GB SSD works fine for me as well, mostly using cloud storage for everything that takes up a lot of space. So it's mainly the processor I'm curious about. Also; Is the GPU performance between m3 and i5 different? I see they both use HD 615 but are they clocked differently? Huge difference?
