you might, but probably not enough to notice. At 50G, the tf/idf stats will _probably_ be close enough you won't be able to tell.
That said, recently distributed tf/idf has been implemented but you need to ask for it, see SOLR-1632. This is Solr 5.0 though. I've rarely seen it matter except in fairly specialized situations. Consider a single core. Deleted documents still count towards some of the tf/idf stats. So your scoring could theoretically change after, say, an optimize. So called "bottom line" is that yes, the scoring may change, but IMO not any more radically than was possible with single cores, and I wouldn't worry about unless I had evidence that it was biting me.
