Question Pretty bad laptop, upgrade it or buy something better? And what to buy?

[Verbosal]

I'm tired of playing games with this laptop I got - I can only get ~75 fps max, with lag spikes...
It can be deconstructed for modyfying thankfully. Recommend me things to replace!
I was told increasing the RAM would help; IT'S ONLY GOT 8GB, so by how much would it help?
I could also buy a PC instead, so I'd be happy if you'd suggest me a good, budget PC. Maybe I should build one?

Here's the specs:
Model: ASUS TUF Gaming F15
OS: Windows 10 Home, latest version
64 bit system ofc
CPU: Intel Core i5-11400H (2.7 GHz, 6 cores)
Motherboard: FX506HF 1.0
Ain't sure if there should be two GPUs, but here's what device manager says:
-Intel UHD Graphics
-NVIDIA GeForce RTX 2050

I'll be sure to list anything else if it'd help You determine what's best!

What is your max budget?

Unless you seriously need portability, laptops are not ideal for gaming. A PC would give you more bang-for-the-buck and also more easily allow individual component upgrades in the future.

Definitely add memory. Another 8GB should work just fine and gain you a lot of minimum FPS and reduce stuttering if you are running a single channel config now.

But the GPU and CPU are not replaceable.

CPU is still decent though. Just an entry level GPU.
