G5 1.8 Ghz Dp Audio Options

[Sedone]

Hello All,
Well I didn't do my usual in depth research before buying my new computer this time and replaced my G4 Quicksilver with the new 1.8 Gig DP G5. I had two M-Audio cards in my G4, the Audiophile 2496 and the Roland VM 3100 Pro/ R-Bus Card both gave me more than I needed. I bought my G5 with the impression that the PCI-X slots were different and the regular PCI slots would still be the same. Nope, then I see that M-Audio has an upgrade path, great. Now, I start reading various post as to the problems people are having with the 1.8 DP; it works for some people and for others it doesn't. Can anyone elaborate on what the problem is exactly? I am waiting for a call back from the M-Audio tech guy to decide if I need to get a new card or a new computer so any advice, stories, second hand stories would be appreciated so I have more ammo when they start pointing fingers at each other (Apple and M-Audio.)

Another question is, does anyone have any experience with other manufacturers sound cards? It seems that this may be an M-Audio only problem.
TIA Oliver
