For an extra $2.50? Max Payne 3 is 100% worth it. I paid $60 last year when it came out, and it was one of the few releases I didn't feel like I should have waited for the price to come down on.
The L.A. Noire DLC is more of the same of the regular game, which is to say that it's very well written content with incredibly high production value. All in all it's like another 20% of game that fits directly in with the story, and even improves it in some ways by including hooks to later cases in the game.
From what I can see, the edition in the bundle is the full, complete game, including all of the DLC, so you shouldn't have to worry about that. (Assuming we're looking at the same store page)
Wanna go crazy? For an extra TWO DOLLARS you can have GTA4 as well, one of the best written games of the past console generation, as well as being a ton of fun.
Is it this bundle here because it's saying it's the complete LA Noire
