So, as others have said, it would help a lot to know what your budget is, and what you consider acceptable (properly lies in the eyes of the beholder), but I went through a similar exercise a few months ago (maybe even a year now...), so I thought I would share.
First, along the lines of previous suggestions, I personally started by googling 'best gaming laptops' and 'best budget gaming laptops' and so forth. I was hoping to spend ~$1200 (US), so I knew I was not going to get a killer machine, but I hoped to find something acceptable. I am fortunate to have a decent gaming desktop, so I didn't need something that would do everything I needed, just decent performance at Ultra or a step down in Firestorm.
There are a lot of options out there for $1000 and up that looked like they wouid meet my needs (decent i5 processor, decent graphics card, 16GB of memory). I also had other criteria, such as relative light weight (I have this thing sitting on my lap!), not looking like some geeky teenage gamer boy's wet dream, and reliability (for better or worse, I worry about some of the really cheap brands). I read a ton of reviews on the models that looked promising. I was fortunate that the model that rose to the top, a Lenovo Legion, was carried by the local Best Buy, so I could check it out in person; reviews had dinged the lower-end Legions as having dim screens, so it was great to see it in person (it was fine, lol). Unfortunately, Best Buy did not offer the model I wanted, so I had to order from Lenovo, and even more unfortunately, they bizarrely did not offer the model I wanted in a combo with the highest-end GPU of that level (GTX1060/6GB RAM) and 16GB of RAM, so I ordered RAM separately and immediately upgraded that, adding ~$100.
In the end, I think I paid ~$1400, and the system has performed very well (plus, lighted keys, woohoo!). Honestly, my desktop is older, and though it has a high-end i7, it also has a GTX1060/6GB (though the desktop version, of course), and is not that far ahead of my laptop. So unlike what some of the threads referenced say, I do feel you can find something that would serve you well for not a massive outlay, of course depending on your expectations.
Sure, I prefer using my desktop, with the bigger screen and a mouse, and better cooling, but with my laptop I can sit on the couch with my family rather than going downstairs in my room. Also, I got a model that I consider portable enough to take other places and use as a general laptop, so it has use beyond SL (I am assuming this is why you want a laptop, too?).
One other thing, in some of the threads referenced earlier in the thread, they mention cooling issues. This can affect performance and also comfort, if you put the laptop in your lap. Also, having it in your lap can exacerbate the heating issues, especially if you use a pillow or blanket under it. I also researched a laptop cooler, and use that all the time. It drops the CPU and GPU temps quite a lot when I use SL, preventing throttling and keeping my laptop from becoming uncomfortable in my lap. I also am very careful to support my laptop in a way that does not block the fans on the bottom.
Hope this helps! Good luck!
