[linux-audio-user] Need a new 'pooter

Hi all, I have become reasonably familiar with Linux, and recently completed the transfer of all my existing MIDI compositions to a working setup based around RoseGarden. I have also started experimenting with software synthesisers, ZynAddSubFX being a particular favourite of mine. However, the problem I now have is processor bandwidth. I seem to frequently run at more than 70% (as indicated by Gkrellm) and just a sniff above that and things start to sound really horrible. Also, the on-board sound card really can't manage the quality I want, either for recording or playback. The obvious solution is to build a completely new system specifically for sound work, but I am totally baffled by the choices. MB, Processor, Memory, Sound Card, and on, and on... Can anyone suggest where I can go to get this all put together? I don't mind paying for a GOOD system, and apart from the fact that all my files MUST be in an open format I'm not too fussed about which distro/apps to use. Of course, not only do I want to know what to get, I also need to know where to get it. Somewhere North of the Isle of Wight would be a good start! -- Bungee
