Computer Recommendations

You're welcome. That gives you a powerful CPU and an entry level GPU good enough for most games, a decent HDD and sound card

That graphics card is pretty weak, she doesn't really need a 980 but your choice is hardly great for newer games. I would still suggest a 960 or 970.

Yeah, well its actually enough to play Fallout 4 at 30FPS - I don't personally use it because I have a more powerful card I got for free, but it works well enough for what she's asking, Fallout 4 is not very graphics hardware intensive, I can play it on an HD4000 allocated 512MB RAM. And no, but you can add a wireless card. Really for a desktop wired connection is best.

There's internal wireless cards (which is the better choice), or the plug-in USB ones, which are cheaper but not as fast. I had to use a USB one while waiting for a new network card to be delivered, so I can say from experience that the USB ones aren't terrible. This is all assuming that you already have a wireless router. If not, you need to pick one of those up too. But again, as with either network card, they aren't really expensive.

I play Fallout 3 and can probably play Fallout 4 too with my cheap laptop integrated graphics but it would be lots more fun with all the eyecandy turned on to max. Btw, getting a new computer myself soon too.
