I’m running it on an i5 with built-in GPU (8GB), but this is just a test set. The quad-core is powered enough that the intel graphics works, and if using Jack Audio I can even get about 20 modules working plus Chrome. It does stutter if going much beyond this though.
EDIT: Has anyone considered an IcarosDesktop AROS compile? It’s a fast OS, but just 32-bit so only 4GB.
