Macbook Pro Purchase Question

[winglakedesign]

Hello everyone,  

 

I am about to purchase a new MacBook Pro.  Mine current MacBook Pro is  2015, Intel Core i5, 2.9 GHz, 8 GB MHz, Intel Iris Graphcs 6100 1536 MB.  Whatever all that means....I get the swirling rainbow often because I run Affinity Photo and Home Designer Architectural along with a few other things being open at the same time...mail, messages, etc.   

 

So - time to upgrade.  I don't know which is more important to help run programs quickly - Obviously - I would like the upgrades on all - but it's already so expensive so wondering if the combination of standard and some upgrade will be okay.  I have  design business and use Chief Architecture for floor plan and furniture layouts to present to clients. 

 

1) 2.6GHz 6‑core 8th‑generation Intel Core i7 processor, Turbo Boost up to 4.3GHz (standard)  vs 

2.9GHz 6‑core 8th‑generation Intel Core i9 processor, Turbo Boost up to 4.8GHz

 

2) 16GB 2400MHz DDR4 (standards)  memory vs. 

32GB 2400MHz DDR4 memory

 

3) Radeon Pro 560X with 4GB of GDDR5 memory (standard) vs

Radeon Pro Vega 16 with 4GB of HBM2 memory vs 

Radeon Pro Vega 20 with 4GB of HBM2 memory

 

I was originally thinking of doing the upgrade to the i9 intel processor - only but then someone mentioned upgrading the graphics card. 

 

I am sticking with Mac at this time because it's what I know.  Can anyone advise please?  Thank you so much!
