Do you happen to know a good gaming laptop in the price range 600 euro to max. 900 euro? It should have a good graphics card and games like Battlefield 5 should run smoothly on relatively high graphics settings.
I think the Lenovo L340 Gaming is good
You have to spend 900-1000 euro to get that.
BF5 smooth in high settings?
You need something like a Ryzen 7 3700U + 1660ti mobile. At least.
Would an intel i5 core be sufficient?
It depends on which one. You definitely need a better GPU than the one I mentioned.
Intel® Core ™ i5-10300H processor (up to 4.5 GHz with Intel® Turbo Boost Technology 2.0, 8 Intel® cache) is that enough?
Which GPU is inside? How much ram?
8GB RAM
GPU: GeForce® GTX 1660 Ti with ROG Boost (if that's GPU, don't know about abbreviations)
Is the RAM expandable? If so, how many dimming slots does it have?
8GB Ram is not enough. You need 16. Can be bought for ~ 35 euro, but you need a free slot. From the rest it fits.
A 1650 ti with 16GB RAM would still be possible
No, the card is too weak. It should be at least 1660ti.
What has happened to the question now?
Can you expand the ram? How many slots does the laptop have. Then the problem would be solved if you can expand the ram.
