GAMING PC: Will this suit my needs?

I've found a gaming PC tower only, and I've asked around to see what my friends think and they've said they give it the heads up. But I want a more sophisticated answer than "Seems cool, get it." If you know what I mean haha.

So here is the PC I'm considering getting:

I'm aware it comes with no operating system. I will buy windows 8.1 separately. Also please bear in mind I'm no computer geek so I don't really understand much about pc's and their "internal" side. But I have researched the graphics card and it got a 7/10.

I will be using this for multipurposes. Minecraft, Sims 3 and sims 4 and obviously things like microsoft word, internet youtube etc…

Dual core 3.9ghz seems to be above average but 2gb graphic card was not able to support high end gaming

Yeah, this pc will suffice. But don't plan on playing anything hectic like battlefield 4 on it, that **** would explode.

The GPU is on the low end. You will probably be able to run games on low settings. A GPU like AMD R9 or R7 260x will be better.
