MarioD has it in a nutshell.

I am using 24 gig of memory on a rather large machine utilizing Win 7 Ultimate 64 bit. When editing video, I can take advantage of my '580 cuda cores' with the GTX 580 and get amazing processing speed in Avid or Adobe Premiere. This does not call too much on my 24 gigs of ram. On the other hand, if I load up Vienna Symphonic Orchestra, along with Symphobia, Ivory Grand, Omnisphere .... etc, etc.I will be utilising a great deal of my system ram, far more than I could achieve with a 32 bit DAW.

In Studio One 2 with 64 bit I use all of the VST Instruments I need along with oodles of effects processin,g mixing and mastering tools. No problem whatsoever, 0% latency thanks to Xonar Essence STX soundcard. I don't have to mixdown to audio tracks anymore while tweaking around for the right mix.

Please forgive me for seeming to boast about high end gear. I saved and worked long and hard for what I have managed to accumulate. It will all be out of date probably next year.

I love B&B .... There is no other concept that comes anywhere near it and long may it develop. I too still keep with fondness the original B&B floppy disks. I have to suggest though .... 64 Bit will have to be offered to take advantage of VSTi's within the software.

Thanks for input everyone.

:-)
