I had to go the laptop route bc I am teaching English in a foreign country and need something I can move back home with easily in a year or two / take with me on trips. It's a shame bc I know that a desktop would be so much better for everything excluding mobility, but I hope that this machine will do well with Arma 3. I am so excited, mostly for the helicopters as I love to fly them in games, but also for the realistic scale and highly detailed terrain for infantry combat. Thank you for your reply
