I'm assuming it depends from the size of your template (i.e. how many samples at a time you're using). For not huge templates you can already run kontakt fully purged off the SSD, but I would assume with this the limiter would be pretty much entirely the CPU... still I don't know of anybody having done any DAW tests with XPoint and large sample libraries (say, Spitfire etc.), would be interesting to see what kind of polyphony a high core CPU with this would be able to achieve...
