Have you already purchased your parts? If not, I'd recommend holding off until we get more info from you. At first glance, that is looking like a very unbalanced computer. Can you give us more info about intended use? Is it purely for gaming? What resolution monitor? What games does she play?
Here are my concerns:
1 You're building using an outdated socket type for motherboard/CPU. The ones you have chosen are still quite powerful as they are only one generation behind, but as you are building a new system, and it appears to be within your budget, you may as well get the latest generation.
2. For gaming, that GPU is under powered. For extremely low budget builds, that is one of the better cards, but you will need to turn down the ingame settings on most games to get steady FPS in most titles.
3. The HDD is massive, but only 5400 rpm. Not a huge deal as you are only using it for storage. But the standard really is 7200rpm. Like a said, this isn't a HUGE issue.
4. The SSD also is massive! Do you need one that big? I don't know your intended usage, but for example in my own system I get by with a 256Gb SSD. That would be the smallest you'd want, but maybe consider dropping down to even a 500Gb, especially considering you have a LOT of HDD space for storage.
5. That PSU is great quality, however, way more power than you need. It'll ultimately depend on what GPU you end up deciding on, but 850W is a LOT of juice! You can easily save some money here. 550W-650W range is probably what you'll end up needing.
If you can provide your budget, and answer the questions above with regards to intended usage of the system, we have a lot of people in the forum who are very good at suggesting part lists! Hope this helps.
