If its’ not too late here’s a couple more ideas. I agree with all the above comments, you can’t go wrong with the recommendations.
The new Alienware R3 laptops are really slick, to me the design is the equivalent of the Razer, and just as thin and light now. Pretty much same price and performance. I’ve owned about 6 Alienware laptops that I’ve used with TD and liked the performance on all of them. Downsides have been size and design, but again that is not an issue with the new versions.
I’ve also owned several Blades, a number of MSI, Gigabyte, ASUS a Mac and a Surface, all of which got heavy TD use. The Mac is really nice as a machine, but as stated above just can’t compete with the others. The Asus, Gigabytes and MSI have all been great as show machines, solid performance and good cooling. The Blades are really nice, but in my experience with heavy use they tend to overheat and cook batteries. Even the new ones have this problem, at least according to my experience and others I know. Best advice is to replace the battery every year, likely good advice for any laptop used heavily at full performance.
It all really comes down to what variables are important . . . size, cost, performance, noise and style. Hands down the Alienware and Razers are the nicest designs and best built. Others perform just as well for less cost, but with maybe not quite as good of build quality and aesthetics.
For me, I look at how I’ll use it. If I’m on the road a lot, maybe touring, and need a light load and quick set up then I’ll opt for a Razer or AW. If it is for studio work or larger installation usage then one of the others.
Finally, my latest laptop is an ASUS G 14, which just came out. For me it hits a great sweet spot of size, price and performance. Small enough to use on most airline seats, great battery life, RTX 2060, upgradable disk and memory at a price of $1450.
Oh, and one more thing. Yes, laptops depreciate quickly. My strategy has been to get 0% financing (Dell, Bestbuy, etc) over 18-24 months. I treat it as a lease and then upgrade after a year and half or so. I can sell for 1/2-2/3 of what I paid, pay ~$125/month and always have the latest hardware
