Apple is swapping out my machine for a 2019 model I currently have an 2.7ghz Intel HD Graphics 530 and Radeon Pro 460 4 GB. 16gig ram standard. I know I want to go with the i9 2.3ghz 8 core machine just debating on what GPUs I need. Is the basic Radeon Pro 560X with 4GB of GDDR5 memory a big step up from my current 460? I mostly use my computer for trading stocks. I have multiple charts open all day long day after day. Usually day 3-4 my computer slows down way too much that I can't use it without restarting. My ram is around 13-14 gig at all times. Would it be smart to get 32gb ram and what gpu? Radeon Pro 560X with 4GB of GDDR5 memory Radeon Pro Vega 16 with 4GB of HBM2 memory Radeon Pro Vega 20 with 4GB of HBM2 memory I could possibly go the egpu instead of paying 250-350 more but don't know if id use it that much. The 2016's do seem a bit underpowered compared to what they have now so its nice having options. Thoughts?
