I've been using my 5 year old core i5 desktop with 8 gigs DDR3 for work until now. I am thinking of purchasing a new laptop so I can do more mobile work. The cheapest core i7 laptops are about $600-$700 but don't come with a bunch of memory or an SSD drive. At Costco they sell an ASUS Republic of Gamers laptop for ~$1,100 on sale, sometimes $999. It has the 8th gen i7-8750H, 16 gigs DDR4 2666, GTX1050ti with 4 gig memory, and then a 1tb drive plus a 256gb SSD. There are other things like a good battery, monitor with fast refresh rate, etc but the main hardware seems to all be there. I also believe it comes with Windows 10 pro vs the home editions like most of the cheaper ones.
Any reason not to buy the ASUS gaming machine? Look at something else? I'm looking to have this for about the next 5 years, possibly longer.
