Hi guys, I'm new to this forum and will soon be purchasing my first mac ! My uses are mainly for photo editing using Lighnroom,web browsing, youtube and some spreadsheet work. No gaming. The Mac I want is the Imac 5K with following specs: - i7 - 32GB RAM (3rd party) - 512GB Flash storage - AppleCare Big question is regarding the graphics card. Since I don't game at all, is it really necessary to get the 4GB GPU ? I was at the Apple store yesteray and saw the base iMac 5K and seemed quite OK with lots of apps open and running a 4K demo video. I am planning on keeping this mac for 5-7 years and really want to make sure I'll be happy with it. I'm concerned with 4GB GPU running hot (even idle) and reducing overall reliability. I would hate to have a failure right after AppleCare expires. Thanks in advance for all the advice.
