Well i am looking to get a big gaming laptop that i can keep for some years. Due to the nature of my work(ship officer) i cant move around a desktop all the time so i am looking for a really good gaming laptop.With budget around 5000 eurosI was looking around and found a few high end ones like msi gt70 2OD 039US and alienware 18.A big difference that i see is the dual graphic cards on alienware 18, does it rly change the performance so much that is worth it? Would it be a lott better to have dual gtx 780m for future and mire demanding games?
