That's actually a really good laptop, if you're concerned about running Fo4 on that thing don't be, you should be able to run it on high. I suspect it'll last you a good 5 or more years. My laptop can run Skyrim with 70+ mods on low settings at an fps of about 20-30 and I'm sure Fallout 4 on low will be similar with minimal mods, so I'm not TOO worried (though I am a bit).
