I just bought a gateway NV5207u below are the specs.
I want to buy the Sims 3 for it .I want to be sure before I buy since you cannot return it once it has been opened.I tried posting this on the forums on the Sims 3 website,unless you own the game and have a serial code you cannot post on the forums.The system requirements section on the website does not list what it needs to run on windows 7 .I’m hoping to find someone on here that has some experience with the game and windows 7.I will also link the system requirements part of the website for the game.
