Bad Av Card?

#1
When I turn my machne on I get a screen full of green vertical lines . MacPro 3.2Hz x 4 core, with ATI Radeon HD 5770 graphics card with 1 GB of GDDR5 memory. I was told that it was a bad AV card and not worth fixing the machine. That seems crazy. Anybody got something else?
Thank you.

Who ever told you that it wasn’t worth fixing is wrong. I found the part you need here --> https://www.powerbookmedic.com/Mac-Pro-ATI-Radeon-HD-5770-Graphics-Card-p-65453.html
That site even has instructions on how to take apart your device so you can DIY. All for under $200 US.
Bless your heart!
This guy was absolutely sure of the cause, of the complete lack of replacement parts in the universe and the only other comment was , "it's old and not worth the money to repair." I am overjoyed that there are alternatives other than my next 3 SS checks.
Does this problem seem like it is a AV card issue?
I thank you, all of you, for being out there. I will report back
