Alright, Im completely upgrading my setup. Right now, its looking like:

Symphonic Orchestra Silver (20-24 vst instruments at a time)
3 M-audio 1010lt soundcards for 24 track out
24 ananlog mixer

I would like to know what system requirements you would recomend to make all of the above usable (no glitches etc). I was considering:

HP pavilian d4100y series
Intel Pentium D 830 3.0ghz dual core processor
2GB DDR-2 - 533mhz dual channel SDRAM
250GB 7200rpm Hard Drive

Is that pc plenty, barely enough, or just plain won't cut it in your opinions? If it won't, what specs would you recomend?
