I got horizontal lines on my display and error 43 on device manager. This mostly means The VRAM on my GPU has died. I am fine with 1080p gaming so repairing the GPU is not an issue for me if it is cheap.

I will mostly buy a used GPU. Should i wait for Nvidia 50series to launch or splurge on a used 3090?

GPU: MSI GeForce RTX 2080 Gaming Trio 8GB

Edit: Also are there any places i can sell my GPU for parts.
