we have a saying, "using a sledgehammer to crack a nut". i'm sorry to say it but it sounds like for what you want an Amiga to do we need the opposite expression.
what would that be?
"using a nut to crack a sledgehammer"?
The new boards are for whatever old boards are for. For doing Amiga things. If you want to do PC things why not just use a PC. There. I said it.
