That is a good build and like Vegetable said make sure the PSU (power supply) are decent brands (corsair, evga, ect.) you should do some nice gaming with an RX480 or a GTX 1070 (1070's about the same as a 1080 for less $$) but also if you get the PC do a desk health check and make sure the HDD will last you, I had a used drive and it failed with my data not backed up, so if the drive has been used for a while either have a backup or get a new one. Otherwise that build is good.
