while it's possible to install a 3090 (370 watt power draw)  in a z800 physically, even  with the optional1100 watt power supply

 

you will exceed the z800's pwr supplies GPU rail limits not to mention the card will be severely bottlenecked speed wise due to the z800's pci-e 2.0 bus and the available cpu's in short the 3090 will perform somewhat better than a 1070-1080 (non TI)
