Beside informative content, the host 'Steve' has very nice voice and accent. Always enjoy your videos. In one of your video, I heard that the channel is not yet making much money which is quite surprising when looked upon the videos' quality. I hope that the host's love for the channel shall remain eternal and soon you guys would receive the money you deserve.
As for vote: Andrew's Bezoar must be most worthy of the upgrade as the system sucks both on CPU and GPU end.
Though the vote goes for pity, the upgrade I love the most is the Evan's 'Coffee Pot' being receiving r5-1400 + GTX1060-3G as this is a very optimized and budget-friendly rig. Also, I bought the same last month.
Anyways, best of luck to both of them.
