or buy a 1-2 year used Asus Rog laptop . . .

I bought mine for 799$ new 2 years ago I7 proc
8GB memory
128GB ssd
1TB storage drive
Nvidia 560 1.5GB graphics
game runs on mid-high setting np and scored 6500 on the 720P bench
for budget gaming and being able to be mobile it was a great deal.

Plus if he need to build a desktop 1K ain't gonna cut it if he needs everything . . .
Like Windows license
monitor
case
PSU
and all the little things that go into a build

and a pre made that's decent 1K will barely cover you . . . if the OP is Canadian and has to pay 13%
tax meaning their actual budget is like under 900$ its not worth it for a desktop . . .
