In a large mixing bowl, beat the softened cream cheese with powdered sugar until smooth and creamy, about 2-3 minutes.
In a separate chilled bowl, whip the heavy cream until stiff peaks form.
Gently fold the whipped cream into the cream cheese mixture until well combined and no streaks remain.
Spread the cream cheese mixture evenly into the graham cracker crust, then top with the peach pie filling, spreading it to the edges.
Cover the pie loosely with plastic wrap and refrigerate for at least 3 hours or until firm before slicing and serving.
