Hello

I am looking at a larger budget laptop and I hoped for some opinions:

A.) Hardware - cpu i9, max ram single TB disk (no raid 0), config is xps or alien
B.) OS - dual boot win10 (gaming for Teens), Debian, live Kali & live TAILS (for myself).
C.) Software - League/Diablo/etc Games, ANN & ML, Bitcoin mining, Green/Whitehatting, Matlab & science apps

It has been awhile since I looked into hardware & gaming so I hoped for some opinions and experience for my questions & clarification requests:

1. Alienware (16 gigs) vs XPS(64 gigs) is very skewed in system RAM - why no 64 gig alienware?
- I assume multitasking (xps) is the reason as alienware is for a single (1) game at a time?

2. As Alienware videocard is far superior to XPS is gaming proportianally inferior to multitasking and vice versa?
- I suspect the xps gaming will be faaar worse than Alienware multitasking.

3. Is overheating and heat-on-lap discomfort a problem?
-I do not wish to have extra lap boards with coolers and fans

4. The various XPS systems are probably linux compatible where Alienware is probably not compatible?
4.1 Particularly the NVMe RAID 0 configs are not Linux compatible so I chose 2TB PCIe Solid State Drive single disk to bypass the dualboot issue - issues?
4.1.1 What is the game quality loss by not using RAID 0?
4.2 Is there any other known linux hardware issues with Alienware or XPS (like the old winmodem days)?
- I do not need linux OS for whizbang gaming I want CLI workhorse CPU & FPU.

Please let me know what you think and if you have any ideas or comments that might have bearing.

cheers
