New Homemade Alfredo

I made a new homemade alfredo recipe today from All Recipes and I think it's way better than the previous recipe I made.  I have to say, I'm pretty happy with it.  I made a few changes though.  Instead of using garlic powder, I used about 3-4 cloves of garlic.  I also used 1 1/2 (8oz) cream cheese instead of just 1.  It just seemed like it was lacked creaminess.  I added shrimp to mine as well.  I normally use ground turkey/beef but thought I'd make it a little different today.  Oh yeah, I added a little cayenne pepper and Zataran's Cajun Seasoning to it.
