Dell has a gaming laptop for sale and with another discount, I could end up paying around $450. How well would it work for two or three screens set up?  I am working on my PPL and want to practice routines and eventually use this for instrument type flying. Nothing too fancy but I do want it to be fairly realistic. 
 

I am actually a Mac user but have old CH yoke and pedals and don’t want to spend too much money on a Windows computer  I am fairly certain the CH gear won’t work with my M1 Macs so I figure I need to do an upgrade somewhere, either controls or new PC and am partial to a laptop  

Thanks!  Here’s the laptop. https://deals.dell.com/en-us/member/productdetail/er6w?AID=1225267&cjevent=88df7743004a11ed80fc01100a82b824&publisher=&cjdata=MXxOfDB8WXww&gacd=9614781-23761182-5750457-265988609-127889515&dgc=af&VEN1=12578053-1225267-8734a8a8004a11edb1ebf23d2a5cf8980INT-Slickdeals%20LLC&dclid=CKnWtJGn7vgCFRC70QQdgfcAHg&nclid=nN6ErK2ug-BEtc6X_w2XsAOzM-kJ4qLbxigylQL6SrJzmG9OWh9ypTSH2gJ5L78r
 

I doubt the 3050 can handle multiple screens with only 4Gb VRAM. Also, the SSD might be a bit small. Here are the system requirements -- https://www.prepar3d.com/system-requirements/. As you can see, the laptop is at the minimum end of them.

It will run MFS at mid-high settings at 1080 (maybe even 1440p) but you can forget multiple monitors with that hardware (not that MFS really supports multiple monitors yet). As regards P3D, no longer a user but again I doubt you'll get smooth performance trying to drive 3 monitors with that hardware.
