Preheat oven to 325°F (163°C). Grease a 9-inch springform pan.
In a medium bowl, mix graham cracker crumbs, sugar, and melted butter. Press into the bottom of the pan.
In a large bowl, beat cream cheese and sugar until smooth. Blend in vanilla. Add eggs one at a time, mixing just until incorporated. Stir in melted white chocolate.
Pour half of the batter over the crust. Spoon raspberry sauce over batter. Pour remaining batter into pan, and again spoon raspberry sauce over the top. Swirl batter with the tip of a knife to create a marbled effect.
Bake for 55-60 minutes, or until filling is set. Cool, cover with plastic wrap, and refrigerate for 8 hours before removing from pan. Serve chilled.
Notes:
Make sure to let the cheesecake chill completely for the best texture.
