Dell has a Promotion going for a Precision Workstation /w 2.8 DC P4, 160 GB sata HD and a free upgrade to 4 GB 667 MHz DDR /w Windows XP 64 bit. My current Daw is a SC P4 3.2 GHz /w 3 GB Ram but running on std XP. And 1 gb of ram isn't really being utilized. I have an E-Mu 1820M as my audio interface. Course I'm not sure if it wasn't Overkill because i really do not use any of the In/outs. The music I write is purely PC based all coming from Vst samplers and synths. If I purchase the new system I would still use the old one to share some of the processing on some of the larger projects. So I have a few questions. How is windows XP 64 holding up as a DAW OS? How are the programs and drivers for it? If I plan to use the new machine as the core until and the current DAW for extra processing, would I still need the high end audio interface allowing me to move my 1820m to the new DAW? As a side note Emu only has beta 64 bit drivers for their AI so far, so that might play into the equation a bit. If I do need it, what would be a good interface given my music writing style of not really requiring and external input nor the need to output much other than to my headphones? Any input will be much appreciated.
