Hi i have dual gtx 980s on a msi z87 gd65 gaming mobo with also 16 gb ram. my CPU is an i5 4670k overclocked to 4.3 ghz. i am just wondering if my system is being bottlenecked due to the fact i have 2 very modern powerful cards but a pretty outdated CPU. i only game on my rig but i would like to know if there would be any point to buying like a i7 4790k even though i only game on my rig. cheers
