Have a strix rtx2080, same as my friend, had artifacts (i heard many rtx's have this problem so maybe it's not asus's fault) and cant even oc it abit without restarting.
heard someone on pcmr reddit that he got perm ban on rma'ing... can't find the link to it anymore but there are many other cases where msi will reject your rma case.
(do note these are from other people, i have never got a msi card due to this so it might be better for you)
