Question gtx 660 bricked after flashing vbios

Today i bricked my gpu. (Gigabyte gtx 660)

Long story short, i had some issues with its performance, and since reinstalling the drivers with DDU didn't solve the problem, i decided to flash vbios (yeah i know I'm stupid)

I don't know if I even did it right, but i downloaded it from the manufacturer's site and run the .exe

Everything was fine, the console finished and wanted to reboot the system. So i did. Since then the bios and system is scuffed, showing colorful artifacts.

Is there any way to fix the GPU or is it dead forever? I also have a second gpu in case i could download some files and use an USB to fix this in bios. Please let me know if there's anything I can do.


I downloaded the bios from:
https://www.techpowerup.com/vgabios/145270/gigabyte-gtx660-2048-130409

My specs:
cpu: Amd FX 6300
mobo: Asus M5A78l-m le
gpu: gigabyte gtx 660
(GV-N660OC-2GD)
ram: 8gb ddr3 1866hz
system: windows 10 64bit

Ok so i watched a few videos about potential fixes for my problem.
I have a spare geforce 8400gs and tried flashing 660 vbios with it, but seems like it won't work because the file is too large. Is there any way to make it work or should I start looking for a new gpu
