Fresh (Frozen) Peach Pie with Sour Cream and Pecans

I still have some of my beautiful peaches frozen from last summer and this is a wonderful way to use them. This pie is easy to make and it comes out nice and creamy and packed with flavor!  Enjoy!
-1 (9inch) pie crust (homemade or frozen) **if frozen, thaw, but do not bake
For Filling:
-4 cups sliced peaches (fresh or frozen) **if frozen, thaw and drain some of the juice
-1 cup sugar
-1 cup sour cream
-3 egg yolks
-1/4 cup flour
-1 tsp vanilla extract
For Topping:
-1/4 cup flour
-1/4 cup packed brown sugar
-1/8 cup sugar
-1/2 cup pecan chips
-1 tsp cinnamon
-1/4 cup (1/2 stick) unsalted butter, at room temperature
Preheat oven to 425 F.  Line a cookie sheet with foil.  Place pie plate with pie crusted in it on top of prepared baking sheet.  Place sliced peaches in the pie shell.
In a bowl, mix well together the  remaining filling ingredients.  Pour over peaches.
Bake in preheated oven for 30 minutes.
While that's baking, combine the topping ingredients until nice and crumbly.  Sprinkle over pie.  Return to the oven and bake for 20 more minutes or until toothpick comes out clean and topping is golden brown.
Remove from oven and cool completely on wire rack.  Slice and enjoy with some whipped cream on top, if desired.  Enjoy!
