Those both look like fine options. As many people have pointed out, you don't need anything extremely powerful. You're not going to be mining on a laptop. You also don't want to be waiting around forever for load times. I recommend getting about 16 GB of RAM and a really nice SSD drive. If you get a Samsung 960 EVO or PRO, for example, you'll really notice the difference. Your computer will be real quick! A desktop computer would be cheaper for more power, of course, but if you need the portability, a laptop is a must.
