Is my CPU a bottleneck

So I just added a second HD 7950 to my PC. It was being added to a MSI B85 motherboard, and an I5 4440 so I expected it to only run at about 70% since the second PCIE slot is PCIE 2.0 16x @ 4x, but the GPUs run at around 90+ % in Metro Last Light. Then I started to have a problem in Farcry 3 where at Max setting I wasn't going over 60 FPS, and my GPUs weren't going past 70% usage while one of the CPU cores is staying above 90%. The other CPU cores are at 70, and 80 % usage. So is that one core the bottleneck?
Thanks

Pci-e 2.0 isn't saturated yet, and most definitely not by a 7950.

Your i5 isn't a bottleneck to a 7950.

You're trying to micromanage something that can't be micromanaged. Different programs/games will use the CPU/GPU at different amounts and also differently at specific areas in the game. Worry less, play games more.

+1 Pci-e 2.0 is still fine for current GPUs. And an i5 is not bottle necking your GPU, it's all about how the game was programmed, different games use CPU cores more efficiently. Enjoy your rig, it is great for 1080P, HAVE FUN!
