I have a specific project that I am trying to spec a computer for (2 channels input, 10 channels output, and a max patch doing pitch analysis on 2 inputs, independent sample playback and convolution on all 10 outputs). 

I am wondering if there are some general rules of thumb that can be used with regard to RAM, processor power etc needed for real-time audio processing, based on # channels, buffer memory used, whatever else? Is there a way, short of trying a patch out on a computer, of predicting if the computer will be powerful enough?

Yes, you can build your patch and simulate multi-channel outputs without having a soundcard with multiple outputs by "assigning multiple logical channels to a single physical channel":

Options > Audio Status > Open I/O Mappings

Have a look at the documentation of The Audio Status Window.

And of course, you can mix your 10 convolution subpatches to one stereo or mono output inside your patch with +~ .

I'm actually wondering about buying/renting a dedicated computer for an art installation. My own computer, which I'm working on now, is an older macbook pro, and can barely handle the patch . I want to spec a new small computer (most likely pc) that I can set up to run headless for the installation. I'm just trying to figure out if there's a way to not over-spec and spend too much, but to be certain it will be powerful enough.
