Is this build good?

Solution
You have a nice build start, but with the RAM, you should try and find another option with either a single 8GB stick, or even better a dual-channel kit that's 8GB. Also, look into getting an SSD to invest in the fast boot times, and later on get a nice 1TB or bigger drive. As for the motherboard, here are a couple of options I found.

1. Red Motherboard, better than the one you want, just refurbished.

2. Blue motherboard, the one you have, just refurbished.

I recommend going with the Red one by MSI, mainly because it goes for a way...

I recommend going with the Red one by MSI, mainly because it goes for a way higher price than the one you originally want, but also because it's somewhat cheaper than the one you want, and better.

Hope this helps!
