Hey Shrish2! I was looking for a laptop within the budget you specified, and I think it would help if you specified some games that you were interested in playing on it.
In other things, I found
this laptop by MSI. It has an i7, 16GB of RAM, 1TB of storage, a great graphics card, and a 15.6 inch display. The only real thing that doesn't directly meet your specifications is the thickness, but if you're looking for a gaming laptop with these specs, you're not really going to find anything that thin.
I hope this helps!
