M-audio Pci Interfaces With G4 Options

[pashaliffi]

I'm looking into upgrading my USB interface to get a PCI card with more inputs, but my G4 is a 466MHz and the M-Audio Delta series advise minimum requirements of 500MHz.. Does anyone have experience of using these with a less than 500MHz machine?

Also, I saw on a forum that the Echo Layla 3G has problems with Logic 7 - does anyone have experience of using it with Logic Pro7?

Thank you!
