Hello everyone! I have decided to build an Alienware M14x R2 and I am stuck on which video card I should choose. Both cards are NVIDIA GeForce GT 650M with optimus the only difference is one comes with 1gb of DDR5 memory and another with 2gb. At first I just figured I would get the graphics card with 2gb; however, upon further research I have heard that depending on your display you may never utilize the other gigabyte, therefore, paying for nothing. The screen will have a resolution of 1366X768 so a 720p display. I do not plan on using multiple monitors, only the one attached to the laptop. I have read that for 1366X768 resolution screens there is no need to have 2gb of dedicated Vram, is that true? I do not want to purchase the computer and then regret not getting the upgrade. I will mainly be using for school but I would love to be able to play Diablo 3 and Starcraft 2 at max settings. With 1gb of Vram do you think I will be able to play those games with maximum graphical settings? It will have a 3rd generation I5-3210m processor, 6gb of DDR3 ram-1600MHz,500gb 7200 Rpm hard drive SATA 3Gb/s. With the 1gb graphics card should this pc be powerful enough to play those two games at max settings? I appreciate anyone who helps me understand this. I know my way around the software of a pc but when it comes to internal components I am at a loss .
