In gaming no, 8GB is about optimum for gaming any more wont make a difference. The problem is the GPU, the 660M is not a bad GPU but it lacks in memory. Most modern games will use over 1GB of GPU RAM when the settings are turned up.
Ya I agree with you zink... The GTX 660 is pretty good. I get pretty good graphics with that... My dad was getting a new computer (desktop) and it will be like a family computer. Specs of it is pretty beast! My dad also said he will upgrade mine to 8gb to 24 gb (i said). But ya... I always end up using the family computer!
