Looking for advice on my First Build before I buy

[waveyboya1]

I've put together my first gaming pc build on pc partpicker, looking for critique and suggestions and warnings if I've got compatibility issues. I already have a hard drive, ssd, windows and peripherals. My limit is $1700 though, which is right were I am. Thanks in advance.

I decided to keep my motherboard, but I looked into it more and you're right, 2 sticks vs 4 doesn't really matter, so I'll get a pair for a bit cheaper. Thanks
