PG Music actually had that same thought. They have in the past published, then changed, the minimum requirement. It's always a moving target though, and there are a few other things on the website and in the documentation that could stand revision.

My point about recommended requirements is that this is very hard to determine. You have an i5. So do I. Mine is seven years old. With so many variations, it's possible to buy an i5 today that blows the doors off the i7 I've been using for production. PG Music for a while were using a minimum single-core score in a standardized free utility, Geekbench, to give a good idea, but even then, it was a rough guess: anything over 2000 for example.

And as I said, if BIAB can run on a system, the only thing you gain by buying a better system is that it runs faster. How fast is that? What's your threshold for patience? It's totally dependent upon CPU first, and storage drive second. Graphics is not even a factor. RAM is a problem only when you choose to run other programs at the same time, which I do not recommend when processing digital audio, ever. And, believe it or not, the audiophile version runs slightly faster.

Does that help?
