sirusx69,
Check out Adobe Audition (fromerly Syntrillium's Cool Edit Pro).
http://www.adobe.com/products/audition/
This is a very powerful, full-featured audio editor/mixer that runs on the Windows Platform. There are dozens of high-end DirectX and VST plug-ins to digitally process audio for just about any application you can think of.

Audition running on a dedicated Core 2 Duo or Quad processor PC with LOTS of RAM and hard drive will give you the same or better functionality and performance as anything the MAC platform has to offer.
I would forget about "consumer" audio hardware and look at high-end digital audio cards such as products offered by Digital Audio;

I've been using all of these products with very professional results for several years.
