I estimated his budget at around $750
Here is a build off the top of my head that I believe might be miles better, given you can wait 2-3 weeks for RX 480.
Apologies in advance. I'm typing this on my phone and it's a bit tedious to look up specific model names and prices. Correct my estimates if they are more than %20 off true values
-I5 6600 ~$200
-Decent well reviewed LGA1151 motherboard for ~$100, micro-ATX or ATX,depending on case choice.
-Well reviewed case up to $60 should be fine unless you are specifically hunting for a certain look
-RX480 4GB aftermarket cooler of your choice ~$220 most likely
-16GB DDR4 RAM ~$60, RAM prices are dropping, so why not? 8GB if you wanna save $20-30 and probably not have any setbacks.
-Good, well reviewed 500W PSU ~$50, very important to spend all $50 on a decent one.
-1TB hard drive $50 OR 240GB SSD $50 and get HHD later
-Hyper 212 EVO I think for $25
-$15 optical drive if you really want it
Total is about $780 ish and can be easily reduced to as low as $720 with 8GB RAM and a lesser case and mobo. But I don't recommend that personally.
