I let you guys decide. I got a MSI R9 270x Hawk video card. Next thing is the cpu. I think the i7 4770k is the best option but i'm not sure reccomend me a good cpu I mainly play arma so a intel cpu would be the best. If I get the 4770k I need one of the z78 boards but what is the best one for gaming? Msi has 2 boards the mipower and a one for gaming asus also have couple of boards. But what us the best combination my budget is 500-550€ thanks
