Is this computer a good gaming build?

Looks.good!

If you don't want to overclock the CPU go with the non-k i5-6600 as it's a bit cheaper and offers the same performance.
You can save a little more in that case by buying ddr4 Ram with 2133 MHz clock speed & a H170 board without noticing any significant difference, but will save around 70bucks
Also when buying a Rx480 see that you can find a model with 2 fans on it, as the reference design is rather uncomfortable

Thanks for the tips, but why is it uncomfortable?
 
1. the rx480 in its 6pin reference variant uses more power than the PCIe slot is designed for. On a good mainboard that shouldn't be much of a problem, however it's not ideal.
Aftermarket designs will probably connect it with a 6+2pin to the PSU eliminating this issue

2. The reference cooler is a single 75(?)mm fan that exhausts hot air through the card out of the card's panel
While aftermarket designs will probably use 2x90mm fans which will integrate the cooling in the case's solution, keeping the card cooler

3. Given that the reference fan has a lot more to do than the big aftermarket fans and needs high pressure, it will run at high RPM and e of a cheap OEM quality thus making it significantly louder

So choosing an aftermarket twin cooler design will be most definitely be very beneficial

The Powercolour Red Devil appears to be everyone's favourite atm
The Sapphire Nitro+ looks good as well
The Asus Strix is never wrong but heavily overpriced imo
Haven't heard anything about the Gigabyte, but they usually put great cards on the market
