Help looking to upgrade

[twinmilll]

Hello All,

I built this PC when the AMD 200 series first came out. I have not bought any additional parts. Basically I am looking to play the latest games. I purchased squad and I am forced to play it on low with 40 fps or less. The game spikes. Arma also lagged insanely hard when I first built the PC. I currently am scared to purchase new games because of this.

Current System

Graphics card: BIOS Part Number 113-1E27100-O48 (Sapphire R9 270X 2G)
Processor: CPU Type AMD FX(tm)-8320 Eight-Core Processor 3.5 GHZ
Motherboard: M5A99FX Pro R2.0
RAM: GSkill 2 x 4GB DDR3 1866
Power Supply: Rosewell 630 Watts

My monitor is a 2420Z 60HZ BenQ

I am not the most computer savy so I did not go in and overclock the CPU or GC

Basically Squad, Total war, and Arma don't look great. I am happy with playing at 1080 but would like to max out everything. I want it to be plug and play and not have to overclock.

Thank you for the reply. Looking to spend between 500$-$1000. I do not have a hard budget. I just want to do what would be the logical approach and deliver the best bang for the buck. If spending a 1000$ delivers more value then spending 600$ than I am willing to do that but I am not looking to chase every ounce of performance.

I'm not sure what you mean by that. Honestly all parts were purchased in February 2014. Now that it is 4 years later I am looking to modernize the RIG. Rig currently has 1TB HD and 120 Gig SSD. Monitor, keyboard, and mouse all still work. I am not sure what I want to do because I have not been following computer parts since the 200's were released. I do not know if it is worth it to upgrade now or wait and then to what extent i should invest for this? I want to play new games on max settings. I am sick of having to turn things down to counter lag.
