Is this a decent gaming pc build?

I'm on a budget of 600 dollars and I just did some research. I was just wondering if I picked out good parts for a decent gaming pc, not overkill, but one that gets the job done? I want to play games like
euro truck simulator, minecraft, team fortress 2, Garry's mod and left for dead 2? I hope I picked right, because people usually underestimate me in everything! Lol once I get a chance to build this ill show them! Anyway, do the parts work together for this?

This is a much more powerful build and is quite cheaper. Plus there's a link to watch him assemble it. Plus with this build you can play much more intense games for even cheaper.
