So I have a base model 2015 Macbook Air 13" which I bought new in June for around $830. I used to love it, but now I realize that having only 4gb of ram and 128gb of storage is really not working out for me. I am starting to get back into gaming, and I have bootcamp on my Air, but honestly the intel HD 6000 just isn't cutting it. Fallout 4 only gets 15ish fps on lowest settings, and GTA 5 is barely playable with around 20-25 fps. Well, I had a friend offer me to do a trade. He has a base model 2012 rMBP which he really only uses as a facebook machine, and he offered to trade it for my macbook plus $200 cash out of my pocket. Comparing the specs, I'm basically getting roughly 2 times the CPU power, twice as much ram and storage, and a much better GPU (GT 650M 1GB). I'm also getting a much better screen, and more screen real estate. The only thing is, I really like how light and thin my macbook is, and I'm worried that I won't get used to the rMBP. I held it and used it for a bit, and it seems alright, but idk. Has anyone here switched from an Air to a 15" rMBP? And is this a good idea or not?
