Hi sifu i need recommendation on laptop hopefully below 3.5k

I’ll be using it for
-stock trading, will need run 3 application at once
-occasionally light gaming eg two point hospital…
-screensize doesnt matter cuz i’ll extend to two monitors

I am using macbook pro 2014 right now, it still functioning well but has become very slow, and i dont want to pay that much for a laptop anymore. I’m eyeing lenovo idealpad5i 15 (11th gen i5) but theres two same model with different graphics: intel and nvidia mx450 not sure which ones better

Not really urgent can wait wait until end of yr
