My assumption is Illustrator would have always been affected by GPU (despite no preference option to choose GPU) but in the quoted update Adobe added some extra features in the way it can be enhanced / users can now choose GPU to use? For the 2015 release of Illustrator CC, GPU Performance is available for both Mac OS and Windows, and it works with various GPUs. GPU Performance was introduced in the 2014 release of Illustrator CC for computers running Windows with select, compatible, NVIDIA graphics processors.

I only ask as everywhere I search for info regarding GPU + Illustrator it's always CC onwards and even on they talk about it being 2014/15 when 'GPU performance' was introduced: Thanks for the you confirm if your 'yes' is from personal experience using Illustrator CS6 with an eGPU? If I should post in a different section just let me know - thanks! With the card I'm open to any options that are affordable and stable. With the case, being quiet is very important to me so if going with the AKiTiO or Razer I will likely be looking to fit new fans etc and I can start asking the more fun questions leading to my first eGPU build If not, then the build would likely just happen a little later as no way I'm affording a Mac Pro so it'll be another Mini most likely. Guessing this isn't anywhere as complex as it feels but hoping the answer to my original question is yes an eGPU will speed up AI CS6 with large complicated graphics on my system. I really have no experience of purchasing Graphics cards so started browsing thinking 'ah yes I just need to look for a compatible card with the most VRAM I can afford!' (imagining AMD, NVIDIA would have a simple range on offer) many different versions of the same cards produced by many different companies later I'm feeling very out of my depth! I don't want to get ahead of myself but options I've been considering (if helps in any way to have this info) are the Sonnet Breakaway 550W / AKiTiO Node / Razer core X and what looks like to be most likely an RX580 of some kind?.
