@zzapzzap said in PSX emulation is incredibly slow:

I could easily upgrade by getting motherboard with Atom D525 / ION2 or Atom D2550 / GT610 installed. Makes sense?

It would be the same issue, as i said if you want to play PSX and don't want to use an arm cpu, you'll need a cpu @ 2.4Ghz as a minimum. If you don't plan to play something "higher" than psx, you should use a raspberry.
