I have a Dell Latitude 5420 Laptop. It has a 2nd-gen Intel i5 with Intel HD 3000 graphics. I have 4GB of ram.
I realize that this will never be close to discrete graphics, but would adding more system ram help gaming performance at all since the system ram is shared with the video chip? Also, how can I tell if my BIOS will support 1600 mhz ram? The memory I have now is 1333, and if it will make a difference, I'll buy 8GB of 1600.
