Custom Gaming Computer Advice?

[Toore]

Hey guys! So, I'm currently running a trash computer, and have been for the past 10 years. I think it's time for an upgrade. I made a computer with these specs:

Spoiler

Case: Cooler Master N300 Gaming Mid-Tower Case
CD: 24X Double Layer Dual Format DVD+-R/+-RW + CD-R/RW Drive
CPU: AMD FX-8320 3.50 GHz Eight-Core AM3+ CPU 6MB L2 Cache & Turbo Core Technology

HDD: 2TB (2TBx1) SATA-III 6.0Gb/s 64MB Cache 7200RPM HDD (Single Drive)
IUSB: Built-in USB 2.0 Ports
Memory: 8GB (4GBx2) DDR3/2133MHz Dual Channel Memory (ADATA XPG V3)
Motherboard: * GIGABYTE 970A-DS3P AMD 970 ATX w/ Ultra Durable 4 Classic, On/Off
Charge, GbLAN, 2 PCIe x16, 3 PCIe x1, 2 PCI
NETWORK: Onboard Gigabit LAN Network
OS: Windows 8.1 (64-bit Edition)
Power Supply: 600 Watts - Standard 80 Plus Certified Power Supply - SLI/CrossFireX Ready

Video: AMD Radeon R9 280 3GB GDDR5 PCIe 3.0 x16 Video Card (Single Card)
WNC: PCI Wireless 802.11n 150Mbps Network Interface Card [+19]

Honestly, I'd just like this computer for fairly weak games, like Minecraft / League of Legends / SMITE. Maybe I'd pick up a few games like Skyrim or CoD now and then, so would it be able to run it? If so, what kind of FPS are we looking at? I'm also thinking about downgrading from 2TB to 1TB, as I don't really use that much space. Any and all advice is welcome.

Thanks guys.

With the type of games you play you will be playing it high to ultra settings in 1080p. Some games might require less AA or non at all to run in ultra setting. Fps will be around 40+ in most of your games

So, would you recommend that I stick with this (It's around 800 bucks), or should I downgrade some items that are unnecessary for the games that I want to play? Also, should I keep the 2TB hard disk, or downgrade it to 1TB?

I made a computer with these specs:

I thought you have it already. Good if not cause there are some parts that better be replace:
hdd: from 2tb to 1tb
cpu: your games are cpu demanding so instead of amd go for intel i5
