I see you figured out that a new laptop is more than this. For gaming, you should get on a desktop with that budget. For example: The Crusher at https://www.reddit.com/r/PCMasterRace/wiki/builds would get you gaming without regrets.
That aside, option 3 is the worst so I won't bother one more word on that or why.
https://www.notebookcheck.net/NVIDIA-GeForce-GT-740M.89900.0.html answers why it lost out to the firegl DDR5 GPU.
So https://www.ebay.co.uk/itm/222770355034 is the winner of these 3 but you should research if those games are even playable on such a thing.
