I have a Samsung laptop with a intel i3 2.4ghz dual core processor, intel hd 3000 graphics, 4gb samsung ram, and 440gb hard drive. I been trying to run higher games for my laptop like Gotham City Imposters and Arma 2 and for GCI i only get about 15-20 fps and on Arma 2 i only get about 15-19. I was wondering if i would get a performance increase if i upgraded to 8gb ram? When i run % on my component usage my processor shows 50% of what my ram usually shows and i was wondering if im not showing my full potential with only 4gb. Is it worth upgrading? Im saving up for a water cooled pc but i need something to hold me over in the meantime.
