Let's see
Note 9, S9 are out of budget
Note8. S8 are old enough to have less performance than mid rangers
One Plus 6T and Google Pixel 3 have SD845 and can be had for 50ish
Mi 9T pro with SD855 might also be available near your budget
Mi 9T with SD730G is for 52k at mistore which is also close to note 8 pro in gaming performance.,

You see, G90T is overall better
G90T beats Kirin 970 by a small margin, and in brand new phones, Redmi note 8 pro has better performance than phones that cost double like Samsung A71, Reno 2 series etc.
