I am new to buying a laptop. I don't play games often, but lately i have been addicted to battle field 3. My work is going to take me on the road for weeks but on end shortly. So I am going to buy a laptop, but I don't know if I should buy a 2gb card or a 1gb card. The screen size is going to be 15.6 with a 1920 x 1080. I don't want to over pay. if i could get some advice I would greatly appreciate it
