RTX 2080ti/2070 failing NVIDIA RTX 2080 Ti DELISTED - Is a RECALL Coming?
i have had 2080ti's and 2070's fail the best card is the RTX 2080 is out performing all pascal gpu's in efficiency. If you are going to buy RTX get the RTX2080 i personally recommend the RTX2080 Evga XC Ultra or Zotac Amp 3fan 
best setting for 2080 +50mhz core / mem default / power 58% 130watt
