Hi there, I am pretty new to pc gaming so I need some help please. I currently have an A6 6400k cpu and aquired a msi gtx 660ti for free that i fitted. It seems to work fine for what I use, but I am after upgrading the CPU. My only problem is I can only put in an fm2 or fm2+ one. So what am I best getting?? The games I play at the min are Arma 3, floght sim steam edition and fm2016. I recently gave the Doom demo a go and it ran great on high settings but my CPU was reading nearly 90 degrees after about 2hrs playing it so I havent put it on again as I am unsure of the heat threshold for CPUs. Thanks in advance for any help.
