If good tools & v. low latency are the issue then consider OSX. PPC or
Intel both have excellent prosumer hardware available plus Apple
CoreAudio is very easy to use. You should be able to reliably work with
64 sample buffers.
Or try Vista, a 25 buck Terratec soundcard and this BSD licensed driver:

CoreAudio live up to promise then you might get all you want.
Keep us posted!

Hi all,
Having just gone through another frustrating afternoon trying to
reduce Windows audio latency, I am motivated once again to think of
alternatives for real time audio algorithm development. I have a
couple applications where a minimum 4.5 millisecond latency is just
not attractive.
I will probably have to use standalone DSP cards for development in
order to avoid this problem, but the development tools on such
boards just can’t compare to Visual Studio.
I have thought before of building a Windows CE target using a
standard Pentium motherboard, and cross developing from a host
Windows XP machine. I’ve heard that the Visual Studio tools for this
sort of cross development are pretty good. I would imagine that
Windows CE could be configured to have much lower latency than
Windows XP.
The problem is that the audio driver model is different, and I am
afraid that finding a Windows CE driver for multichannel audio IO
would be impossible, and that developing a driver myself would be
very time consuming.
Has this idea occurred to anyone else? Is it even feasible? Has
anyone succeeded? Does anyone have opinions on related subjects?
Thanks!
