Soundcraft Signature 22MTK or Behgringer X-touch + MOTU 24 AI


I'm using many hardware synths in my set up and was until now bringing those into an analogue mixer (D&R 900) and then in stereo into my DAW (Ableton). I want to be able to monitor my hardware processed through my DAW effects & automations without having each time to (re)record layer per layer.

So I'm considering to buy either the Soundcraft Signature 22 MTK or to go fully to my DAW buy using a large soundcard (like the MOTU 24 AI) combined with a decent control surface (the X-touch eg).

Anyone's got experience with this? Can you expect monitoring 24channels to even work at an acceptable latency? I've got a decent pc of 2yrs old.
