2080ti and cpu question

[fantasticCG]

Hi guys

My friend has i5 8400 cpu and is thinking of getting a 2080ti will this cpu bottleneck the gpu?

What minimum cpu would be recommended for a card like this?

Thanks

What GPU does he have now? Sure it will likely be a bottleneck but he will still likely see an improvement in average FPS but may see more lows as the card is waiting for information.

1080
