Whey Isolate in place of more expensive protien rich food?

Calories is not so much a problem but budget is (Barring nut butters etc). If your focus is on maximizing the protein intake. (the target in in case is roughly 110 grams a day. What are the issues faced for men and women if they are taking more than 2-3 scoops a day? (just whey isolate/concentrate) no additional additives other than fillers of carbs/fats. i'm open to more natural sources but cost per gram for the complete protein you whey seems to be hard to beat.
