GPU questions

Can you guys recommend which GPU should I get for Raven mining? Currently I have a 3090 which just switch to Raven. I am thinking of buying 1 or 2 more series 30 but not sure if I should go for the 3080 or 3090. 3090 being more expensive but better hashrate. But will a 1060 6GB be a good option since it a cheap card but power consumption is twice compare to the 3090 but cost half if I buy 5 1060 6GB. I am thinking stick to the 3090 since it is for the long run.
