You'll have to wait until July 14th to pick up the game, but God of War III Remastered should be worth it. The game was great on the PlayStation 3 and it looks even better on the PlayStation 4.
Today, PlayStation is showing off the Hades boss battle and it does look pretty. The video runs at a smooth 60FPS at 1080P with the great art showing through in the battle. I'm impressed at how nice it does look and the game was already impressive on the PlayStation 3.
