sad time to be canadian.
For the CPU, the better gaming budget option is the less expensive Ryzen, the R3 3100, wich is like 170CAD here.
I leaned towards a R7 1700 on Aliexpress @150CAD, to get a true 8 cores, but worse memory support, need for a beefier motherboard, lack of bundled cooler made me change my mind. Those points make it less ideal than the R3 3100 for a budget gaming pc.
It performs like a 7700k, for the price it's not bad at all, but I remember a few years ago when top of the line CPUS and GPUs were like 300$
As for budget gaming GPUs I still recommend to my friends used RX480 @ 130$CAD. this price/perfs ratio is uncontested. And it still doing wonders for 1080p and even most VR titles.
