Hello, I am planning to buy an imac for my audio projects. I will use Reason, Cubase, ProTools etc. I thought this specs. is good for me 4.2GHz quad-core 7th-generation Intel Core i7 processor, Turbo Boost up to 4.5GHz 16GB 2400MHz DDR4 1TB SSD Radeon Pro 575 with 4GB video memory My question is: are those specs "too good" for those softwares? Can i5, Fusion drive and 8 gb ram handle or not?
