Upgrading on a budget: help!

[jkacin]

Hello, everyone. I was recently informed that my motherboard, in a lack of better terms, took a dump on itself. I am now in need of a new motherboard and gpu (I'm running an R7 240. It's dire.) I have my old pc parts I could sell, but seeing as it was built for me, I have no way of obtaining boxes besides buying them, to sell and ship them. No one locally would buy them because I live in a not so technologically advanced area. I also have no way of obtaining a steady job because my step dad wants me to work for him all summer (for free, of course.)Any suggestions on what I should do/buy?
Currently I am looking at a refurbished gtx750 ti ftw for the new gpu:$115.
My motherboard choice is undecided but I would like uefi bios and anything up to atx is fine.
$120 budget.
Specs:
Cpu:fx 6300
Ram:8gb ddr3
Mobo:asus m5a78l-m usb3
Psu:evga 500w
3 hdds: equivalent of 2tb 750gb
Optional win10 tp or win 7

Old specs:
Cpu:AMD Athlon X2 340
Ram: 4gb ddr3
Mobo: ECS A55F2-M3
Psu: logisys 480w
Same hdds and os.

For $120 you can get a decent motherboard, just make sure it has heatsinks on the VRM MOSFETs.

This one looks pretty good for your system and costs $80-90.
