Help with re-arm pc!! Ram Ddr3 or Ddr4???

[manolete]

specs:

CPU: I7- 3820.-
VGA: AMD Radeon HD 7970
RAM: 8Gb x 4 (ddr3 - 1600) G. Skills
SSD: 500gb Crucial m4
HDD: 500gb
Motherboard: Asus Rampage IV (DEAD!!!!!) ;(
Cooler: Thermaltake frio extreme
power supply: Corsair TX850W

- My motherboard died because some pins where the cpu goes broke.

EDIT: In the end I decided to buy new parts for my pc, now I am between trying to use my ram or change to a ddr4.
So, what is the most current socket that supports the ram ddr3? or it is not convenient to continue using my ram?

- Regarding the amount of money I have, it is difficult because I have to buy materials for my university career, dentistry (around 1800 USD), in the end I would have between 350 USD to 670 USD, and that I can probably buy the parts for my pc in 1 month (at the beginning of March) 🙁

Pd: the pc is just for playing, like Lol, PUBG, Fortnite, Rocket League, Cs: Go, Black Desert.

I would say to get a new motherboard (or used) ,ram pricings are terrible (especially ddr4) and you would need a new cpu as well while the one you have imo is still strong.
Of course could you sell the parts you still have which would generate some cash back.
