I have an alienware 15R2 laptop with 16Gb of DDR4 RAM, Nvidia GTX 970M graphics card with 3Gb dedicated graphics memory and an Intel Core i7 6700HQ 2.60GHz. Im looking to upgrade it (not get a new laptop but just some stuff inside). I play games that have some hefty system requirements and wanted to get more fps. What would be my best thing to upgrade in my laptop as i feel something in it is lacking? and do you have an suggestions to what i can upgrade to? Thanks in advance!
