I will be using it for mainly at home hooked to my 24" Asus monitor for 144hz. I also will be using it on the go sometimes. I dont care about the screen size, but im wondering if the 1070 is worth getting over the 1060.
Look at the performance difference between the GTX 1060 and GTX 1070 in the following link to Notebookcheck.net. Depending on the game the performance difference can range from a 20% to 55% difference.
Either way I recommend you order the laptop you want from Newegg instead of from Amazon or walking into Best Buy so that you do not need to pay taxes... Unless you live in CA where Newegg has it's headquaters. Or NJ / TN where Newegg has warehouses.
