What component should i upgrade in the near future?

[YourAverageGamer]

Hey, first off I'd like to apologize if this in the incorrect section of the forum. Recently I bought a custom built desktop a while in November in 2014. All the components were brand new and never abused. Here's my gaming setup. None of my components have been overclocked or abused. I'm fairly tech savvy but not as much as most users on this website so sorry if my vocabulary or knowledge is a tad short as I've recently switched to PC gaming.
CPU: AMD Phenom II Black X4 965 Processor 3.4 Ghz
8 GB Ram (7.18 usable)
GPU: Nvidia GTX 660 graphics card
Case: Antec 600
Monitor: Benq GW2255 Monitor (DVI)
Motherboard: MSI 970 Gaming motherboard
Keyboard and Mouse Combo: http://www.gamdias.com/en/p/gkb6000_gms5500/
PSU: Corsair HX650W Professional Series
Hard drives: 1 128 GB SSD for important files and OS
1 1.5 TB HDD for everything else such as download, games, etc.
Sorry as well if I'm missing anything essential. Keep in mind currently I've been living off of F2P games but will be moving on to some paid FPS Shooters. Thanks in advance.

If you're going to use this PC and upgrade it, the next thing to upgrade would be the CPU-Motherboard. You will need to upgrade them both.
