Alooahh

I have problems with my FPS in Arma 3. Mostly running with 20 FPS that are to low for good shooting and gameplay. What is the best Hardware for Arma 3? Which graphics Card is the best? CPU? Is it better working on a SSD? I need some informiations how i can make the performence in Arma better. I got a i7 4770k, R9 290, 16 GB and MSI Z87.G45 Gaming Motherboard. I want to play atleast with 40 FPS on a full Server. Are there more ways to increase the FPS in Arma?
