depends on how much precision you want. I've reccently used the AD7945
12bit DAC for a module that generates CV. For my application I didn't
need any more precesion than that. I'm updating it at about 100KHz and
it should go quite a bit faster than that. order some samples to try.
also, Paul posted something about this on the SDIY list once, look here:
