Since neither detail was shared I can't give a straight answer except to note that 1G is a nice place to be.
I am thinking of adding system RAM to my computer. It's a Toshiba Satellite P25-S5092 laptop with 32MB of separate video RAM. I apparently can't change the video RAM because it's a laptop.
I've currently got 512MB of system RAM and I am considering adding another 512MB or maybe more. Will this help with games?
