I am seriously considering upgrading my 9-year old iMac to a new top-of-the-line 27" Intel i7 CPU, 32GB RAM, AMD Radeon R9 M395X with 4GB of GDDR5 memory, one. However, I heard there were some problems with the new Sierra OS. Does anyone know about these and if they have been resolved?
Also, there seems to be an option to go with expanded flash drive OR a larger HD. I’m using half a TB now on my third drive in my current iMac and since I keep computers a long time, I’d like to plan for future expansion. Would I be giving up performance for capacity if I went for the 3TB HD?
