I am just curious what you guys think.. Im talking a windows eviroment personaly, but mac guys feel free to chime in.

Whats the least/most hard on computer systems?

Here are just a few I could think of off the top of my head..

Nuendo
Cubase le, sx
Pro Tools LE
N-Track Studio (not a top nitch program, but efficiant and cheap)

Cubase seemed to handle everything good on my p4 at 3m latency on my firepod. But Im not sure how it compares to the rest.
