Per un uso basico 8GB sono sicuramente sufficienti anche tra 2-3 anni, per il video editing ad esempio l'attuale versione di Final Cut X ha i seguenti requisiti minimi (magari la prossima raccomanderà 16 GB):
Minimum System Requirements
macOS 10.12.4 or later
4GB of RAM (8GB recommended for 4K editing, 3D titles, and 360° video editing)
OpenCL-capable graphics card or Intel HD Graphics 3000 or later
256MB of VRAM (1GB recommended for 4K editing, 3D titles, and 360° video editing)1
Discrete graphics card required for VR headset support. AMD Radeon RX 580 8GB graphics card recommended for best performance.
4GB of disk space
