If you are slightly adventurous and want a desktop here is a fantastic resource. My son and I built a gaming rig for his 11th birthday using this, I lent a hand but he did most of the work. For ~$400 he has a screaming machine that can easily outperform an Xbox1 or PS4,
for ~ $900 you could build an insanely fast machine, in fact if you aren't doing hardcore gaming it will probably be far, far more machine than you need
