I'm planning on replacing my laptop, i'm looking for one that preferably has an nvidia graphics card or can have opengl 2.5 or better, runs smoothly in general, playing games, or looking around online, and my budget is $600, give me what you think is best for me
$600-$700 gets you Laptops with the following Graphics.
GeForce MX150 "Mobile 1030GT" + 8th gen i5
HD Graphics 620
Ryzen 2500U "Refurbished"
960M + 6th Gen i5 "Used"
$701-$799 gets you something a little more gaming worthy.
1050 GT + 7th Gen i3 or i5
1050TI + i5-8300H
1060 + 8th Gen i3 or i5 "Refurbished"
970M + 6th or 7th Gen i5 or i7 "Used"
Possible a 1060 + 6th gen i5 or i7 "Used if you search locally"
None of these are going to be ultra slim Aesthetically pleasing like $1000+ units you can find now, they will all have faults in some of the following; screen selections, larger bevels, flimsy keyboards, lack of ports and weight. If your a student and in the US contact Dell directly or see what your college/university can get a deal on.
