So this is my first laptop, and it seems to be struggling in the graphics department (figuratively speaking). I already upgraded to 8gb of ram but programs are really laggy, especially when running more than one at once. Games and CAD programs are slow and crash often. I have built a gaming desktop before, but i am pretty new to the notebook game and cant seem to figure out how to beef up the display capability. Are the graphics integrated or something? Help much appreciated.
