I recently put in for a $2500 loan for a gaming laptop but I’m unsure of what exactly to get or what I need.

My budget is around $1500. I don’t mind going over a bit and paying less is obviously a plus for me.

I’m not really tech savvy.

I’m not sure if I need one with an i7-9750H or if a i7-8750H is all i need?
Should I look at HP Omens or MSI or What, and Where to buy, Online or In store?

If online should I go Walmart or Amazon or go straight to HP, I would prefer a physical store but I’m pretty sure that the ones around me wouldn’t have anything I’m looking at in stock.

I really want something that can play Battletech 2018, Dawn of War 2, and the upcoming Mechwarrior 5.
Hopefully without going over budget.

Can someone with expertise help me out?
