Not sure you are trolling or not, but I will bite. One of the very RAM intensive stuff I'm doing with my laptop is that I am using many VMs in GNS3 set up for networking simulation with Linux VMs running Quagga, LiSA, etc thus the more RAM I have the faster and smoother the simulation.
Why so many people go berserk when you say you need more RAM? The new workstation CPU from Intel namely W3300 can support up to 4 TB RAM, RAM amount of 128 GB is practically peanut compared to that.
What do you need, a mainframe?
