For rendering and machine learning tasks, it is important that the amount of RAM is greater than the total amount of VRAM, so for a configuration with four A10s (each have 24GB of video memory), we recommend configurations with at least 96 GB of RAM.
For gaming, we recommend configurations with GPU, 8 CPU cores, 16 GB of RAM and a 160 GB disk.
Streaming configurations are usually less memory or disk intensive. For disk-intensive tasks, we recommend SSD drives (Volume + Volume SSD-based instance type) or Local, otherwise use the cheapest HDD-based Volume + Volume instance type.
