At least 1.8!?!?!
Joelegato man, I have to take exception with your specs you claim are needed.
My old 450 saw many a song produced through it's windows 98 OS and it never had any problem mixing 30+ 16 bit tracks.
Now I use a gighz Athalon with win 98 and get great results using 16 or 24 bit resolution.
Celerons won't do it? Gimme a break!
And what's this about the clarity of dynamic mics...you are a wealth of misinformation.
Spectacle, I would second the sticking to computer thing unless you are prepared to buy a dedicated HD unit like the 24 track Mackies or TASCAMs.
But then you'd need a 24 channel mixer and outboard pres or a 32 channel mixer.
I personally just stopped recording on computer as my main multitracker. Now I use
an ATR60 16 track reel to reel machine and an M600 console to mix on, both are made by TASCAM. It's not that I have anything against computer recording, in fact I enjoy it very much. to my ears nothing in my price range can touch the sound quality/character of a good tape machine.
