I need advice with the CYBERPOWERPC walmart thing

those graphics cards kinda suck. If I were you, I'd build my Pc but it seems that you're new to this. So, your call.

As for if the set is worth it, I'm not too sure. It seems to be the right price for its parts but they're low-tier and won't handle much in the near future. In other words, it's not future-proof.

For $555 build your own. You could build a better machine for the money.

For a little more you could get this one, but building is still a better option:

If it gives you all the specs just buy the gear and build it yourself

Just build your own pc from scratch...then you know what you did, and what you put into it. Plus if you shop around you can always get good deals. If you have the time, and patience to build your own rig then it's very rewarding. Each to their own.
