Why not just make a single really fast processor, even if it had a couple parts to it? Gotta love consumerism!
Mac Master Pro 100 x 200 GHz Gigaquad-Core Intel Xeon with Bells, Lights and Whistles, even makes your bed in the morning.
I've heard some truly drop-your-jaw music recorded on an ancient four track with less then perfect instruments.
I'll give you a hint. "Being a great musician, is not about your equipment."
I will admit that recording is like photography in a way. The better the device is to capture it, the better the chance of getting a great looking photo. A picture of poo is still going to be a picture of poo! It's probably wiser as an engineer to focus on getting a good interface, great preamps and the kind of mics that fit the bill... in my humble opinion.
An observation while I'm thinking about it. I still record on an old, beat up G4 Laptop. The thing started freezing all the time due to CPU drain. So instead of running the newest, neatest stuff I downgraded it to an older OS (10.4) and Logic 7. Now unless I'm trying some really heavy recording with tons of plugins, the thing works great. Just a reminder that they intentionally outdate they're equipment. By staying on top of things, they've got you and your wallet right where they want it!
I've had no issue transferring files between the laptop and the studio's nice computer running Logic 9. Doesn't work the other way around as smoothly though.
