The 3080 I bought was the ASUS RTX 3080 TUF OC 10GB, I can highly recommend this card, it holds clock speeds extremely well and runs very cool and quiet. The highest temp recorded so far is 61c but averages at about 55-57c. Recommended PSU with your current CPU and this card is 750watts running windows-10. I can't comment about VR because I don't use it, the main reason is it makes me feel extremely ill and I don't like sort of being cut off from the outside world. Best of luck with the Steam VR.
