I have 3 laptops for school and light gaming.
2.3-3.2 Ghz (4 core), 8GB RAM, 4GB Graphics
2.5-3.5 Ghz (4 core), 8GB RAM, 2GB Graphics
2.3-2.8 Ghz (2 core), 8GB RAM, 2GB Graphics (touchscreen)
Touchscreen would be nice, but is it worth it? If not, which one is best?
I would go for the 2nd laptop with 2.5-3.5 Ghz (4 core), 8GB RAM, 2GB Graphics. You don't need 4GB graphics card a 2GB would be enough. You would be able to play the latest games there is with the configuration of the 2nd laptop.
