I have a Dell Latitude 7275 (extremely similar to Dell XPS 12) which is a detachable 2 in 1 sort of like a surface pro but mine is rocking a measly Intel Core m5-6y54 processor which runs at a SUPER FAST 1.1GHz base and turbo to 2.7GHz and is all passively cooled.

But it has 2 4-lane thunderbolt 3 ports and I wanna do some very light casual gaming (dota 2, nba 2k20, maybe some apex legends if this cpu will allow for it)).

What is the best possible gpu I could pair with this that would not create a bottleneck?

I was thinking a gtx 1050 but maybe someone here has any experience with this and can see an improvement going up to a 1060 or a 1650 super? (I would already be super impressed with that and I already know a gtx 1070 or higher is out of the question).
