I'm torn between these two computers. I want to be able to play skyrim, fallout 4, witcher 3 with some mods. On higher settings with a good frame rate. And would like to know which one to go with. The 551 has a TN screen and smaller form factor sporting a 2gb gtx960m while the latter has a ips screen with a 4gb gtx 960m. Help would be appreciated.
