i feel your pain. My 1080ti bit it outside warranty too a few months ago. Ended up biting it and getting a 2080s. Great card and DLSS is nice.RMA denied /cry.
MSI doesn't extend the warranty on a replacement (At least that is what I've been told over the phone). 980Ti was from 2016, so it's 4 years now.
Id consider a 2xxx card at this point still...A few rumours out there of initial very limited supply towards the 3xxx series, which will mean hard to find amd premium pricing...I'm totally OK with what I did, but it was months before even those rumours and I wasn't going to stop gaming from March till October/November.
