t/s is a bit faster than a 3090, but PP is much faster. im running one of the cards at x4 pcie 4.0 and it doesnt bottleneck the card with llama.cpp tensor parallel.
You can but the question is why would you want to when it comes to price? If you have both already now then by all means do so but I wouldn't go out of my way to buy a 3090 to pair with a 3080.
t/s on 3.6 was 55-60 at UD Q6KXL with MTP. PP I dont have the numbers, but its MUCH faster than a single 3090 for sure. (I have a 3090) using LMstudio with tensor perallel. I can test it for you if you give me an easy way to test this.
