Both my box and my laptop have 4GB of DDR3. I game, and I have a 5770. My question is on either system is there a need for going more than 4GB of RAM? MY laptop can do 8GB and my box can do 16+. Is there a purpose? I convert Videos, for person use, I game, and I crazy multi-task (Firefox has 50+ tabs all times, I also have a lot of apps open at once).
