It's worth keeping in mind that DSD64 is roughly equivalent to 20-bit 48kHz PCM.
It could be argued that the frequency response extends a little higher than that, but above 24kHz you have to start filtering out a lot of noise.
If you're converting to 24/96 PCM or higher, you definitely have all of the audio information contained within the DSD file.
It's only really worth worrying about bitstreaming DSD if you've got one of the few true 1-bit DACs out there which can play back DSD completely untouched. (and that's not a recommendation to go buy one)
The main reason to be buying/ripping SACD now is because it may be the only format where a surround sound mix exists - though a lot of those have been released on DVD-A/Blu-ray now.
For anything else, just buy PCM. It's higher quality, and it's a lot less hassle.
