I think you can figure that out yourself :P
"CyberPowerPC - Gamer Ultra Desktop"
The name is a give away, this is not going to be good...
The FX-6300 had some problems if I remember, but the main problem is the GPU

It's not at all a good GPU. It's even worse than the 560 Ti
The other Envy has the same problem, it has a bare minimum GPU.
If one tier is too expensive, try the tier below it.
If you google the minimum and recommended requirements for a game, then check a benchmarking site you can easily compare your GPU and the recommended one. For CPU just look at clock speed. For RAM 4gb is enough for anything.
