Hi Guys I was wondering what options i have for upgrading for my i7 imac 2015 4.0ghz. I have 500gb ssd/ flash installed which i wish i had pushed to 1tb (can i add another ssd or upgrade the current) at the time. Also upgraded my ram to 32gb aswell. I use Logic Pro x, and after effects and illustrator etc. Do i have many options to improve my performance further? Would it be worth the extra £?
