Becouse I buyed 1440p 144hz monitor need buy one more gpu. I have gtx 980. I have p8z77 m pro motherboard and noctua nh-d15 and it's big so one slot for gpu can't use becouse noctua is over it. So don't want change cpu cooler will change motherboard. I have 3570k.Is better to just buy new motherboard or motherboard and 4790k. It's just for gaming so think 4790k is't much better than 3570k for today games but in next 2-3 yeras maybe it would.so whats better( konw if don't have 3570k will go with 4790k but I alredy have 3570k). and I have xfx 750w pro psu. will it handle 980 sli overclocked and 3570k at 4.6ghz with 16gb ram 2 hdd, ssd and 7 fans in case?
