I'm interested as to what Thunderbolt audio interface you plan on using as they are pretty thin on the ground right now. As far as I'm aware all that's available at the moment is the Universal Audio Apollo (With Thunderbolt Option Card), Avid HD Native Thunderbolt and The Apogee Symphony 64 Thunderbridge.
Using Thunderbolt of audio I/O is only really needed if you require a massive number of I/O (i.e. upwards of 32ch simultaneous I/O). The Universal Audio Apollo makes good use of Thunderbolt as it contains DSP heavyweight processing. In most cases firewire or USB are more than up to the job as long as the interface if from a reputable manufacture (for USB I would always recommend RME).
Even when it comes to PCIe audio interfaces I can really only think of one that fully exploits the bandwidth of a 1xPCIe slot,

Which can manage a ridiculous 390 channels!
Hello, Salty Dog!
Thanks for the post and I'm glad you asked. Yes, you caught me. I am considering the Apollo. I have a firewire interface currently, but Salty, I am tired of the B word and the L word! BOTTLENECKS & LATENCY. Not to mention, I'm betting on Thunderbolt being around in the future (risk).
I currently run a very humble and quite outdated protools set up. I've been sitting on a UAD Neve card I own for about 1.5 years (yet to be used), waiting for Mac Pro hardware update... Long story...but I digress. Here is what I think...
1. Apollo w/ Thunderbolt = extremely minimal latency and the option to record (live) with some DSP plugs here and there... I don't need the I/O to record many channels at once. I need a good quality interface more so to record occasionally with some (minimal) plugins and NO latency... ok - well minimal.. lol. The UAD firewire devices cannot do this and have bottlenecks.
2. Not to mention the high quality plugs and the lack of bottlenecks, as the DSP will handle those nifty UAD plugs. Like I said, UAD TB devices will have fewer bottlenecks for DSP processing.
3. I think Thunderbolt will be around in the future, but I'm a noob and this is a risk. Who knows?
4. Finally... How I work, but this has more to do with DSP... I produce music for others (mostly). I'm not in a band and don't do a lot of band/live recording (85% of the time). I like to use any and everything to make a song. This includes any software stuff I might have (plugins, vsti's, etc) in addition to recorded tracks (bass, spoons, anything). I do not like to bounce/print/write tracks with any plugins applied. In fact, I don't like to bounce or print anything until I know a song is 100% complete. I am ALWAYS changing my mind, automating, using different patches/instruments and adjusting things. I use a decent amount of plugs, etc., on my current system and its never enough. I feel a bit better knowing that a good deal of quality processing will be handled in the DSP. This frees up the CPU to handle any stuff I might want to throw at it...
My other (music) producer friends say this is not necessary. They say the new (MAC/PC) hardware allows one to throw a ton of (native) plug-ins, etc., on many, many tracks without any issues. I believe this, but I assume things become more (cpu/ram) hungry over time and I don't want to be quite as stuck as I am now... Also, some of those nifty UAD DSP hungry plugs are not native... (off topic, I wish someone made a non TDM SoundBlender plugin.. sigh...)
I'm in no rush to buy the Apollo. I do have a card. I plan on using that for now. My experience with the card will help me decide if the Apollo is worth it. I don't need it for the grand I/O so much... more so for the FAST DSP processing and the ability to record with some plugs sans latency... However, this is a WANT. No a need. I could just buy additional cards (prices have come down). We shall see.
