[SOLVED] Please help me optimize my old computer for DayZ

[Gulmo]

I play on the Day One DayZ server and at times my computer lags really bad. I don't meet DayZ minimum requirements on memory so I believe this is the major problem. But I would also like a recommendation on what components (graphics card, RAM, etc.) I could buy to make the game run more optimally and are compatible with my pc. I built this computer 6 or 7 years ago. Any help would be appreciated. I have listed my specs below. Thanks

My Rig-

Processor: Intel i5 - 4670k @ 3.40 GHz
Ram: G Skill Sniper 8G (It is two 4G sticks for a total of 8G. I have two empty slots left for memory on my motherboard)
Motherboard: ASUS Z87 - Plus
Graphics Card: EVGA Geforce GTX 760
Power Supply: EVGA Supernova NEX 750B 80Plus, 750W
Mechanical Hard Drive: WD Blue 1TB
System Type: 64 - bit Windows 10

DayZ system requirements for Windows -

You are barely above minimum specs on the processor and GPU, so both would offer some benefit if you upgraded them.
Comparing the minimum to recommended it appears that a better GPU (aside from RAM) would be the better of the two choices, since the performance increase from a 4690k to 6600k is not as big as the difference between a 760 and 1060.

I'm on same sort of vintage, upgraded to 16GB and a 1650 video card, made heck of an improvement for games for me. I've not played DayZ though.
I get 60fps in Overwatch (cpu bottleneck), and 50fps in GTAV. Both @ 1080. At least with the 1650, when I upgrade soon, it will still be a half decent card for what I play/do.
