Does it look like a good gaming/streaming pc?

Solution
Looks good. For gaming, you don't really need more than 8GB RAM, I'd cut there and go with a beefier GPU.

I'd recommend going the Haswell route though, take this as a suggestion:

An SSD is currently down to preference since they are still fairly expensive. It will greatly improve boot times of Windows and your games, but if you will use a lot of storage you may just want to get an HDD.

You might consider buying a better graphics card with the money saved from cutting the RAM down.
