I totally feel where you are coming from. I've been in the process of deciding what I wanted to do with my network for the past 2 months. If I were you, I would just say screw all of this until your wife has the baby and life has adjusted to the new addition. It will still be around. It will honestly probably give you more time to plot things out and figure out what you really need.
All in all, if you figure a iGPU will work best for you, you could probably return the motherboard and puchase a new MB plus have some money set to the side for a CPU.
