Is this a good gaming PC?

[Elitefast]

Just wanted to confirm whether or not all my components are good enough. This is the first PC I'm going to be building so any help regarding what I need to whatch out for would be much appretiated.

Along with these components, I will be using an i3 6100 3.2Ghz CPU along with a RX 470 4GB when it releases as I'm trying to complete the build with a budget of £500. I'll be playing games like Battlefield 1, Skyrim, Fallout 4, etc.

Any reccomendations for replacement parts would be appretiated if they remain under budget.

May I suggest going for a prebuilt system such as this on Amazon GAMING PC (Intel Core I5 4460 3.2Ghz Quad Core CPU, NVIDIA GTX 960 2GB DDR5 Graphics Card, HDMI, USB3.0, 8GB 1600MHz DDR3 RAM, 1TB Hard Drive, 24x DVDRW Drive, Corsair PSU, Vantage Purple Gaming PC Case, No Operating System)

In terms of buying a premade computer, I've found this one that I'm probably going for but I'm hesitant as the CPU is an average one but the GPU is really good. PERFORMANCE 4.0GHz Quad Core AMD X4 860K Desktop PC - 8GB RAM, WiFi, 8GB RX 480 | eBay
