I have a Radeon RX 480 GPU. My mobo has a PCIE 3.0 X 16 slot and i have an i3 3240 3.4ghz CPU. However, in GPUz it says that my GPU only runs at PCIE 2.0 when maxed out. Is this because of my old CPU? Some advice would be appreciated. :)
 
Solution
Yes, its because of your cpu. I think 3th gen i3's lacks pci 3.0 support. There is not much performance difference between 2.0 and 3.0 so its not a problem at all.

Thanks, do you think it is worth upgrading my CPU for the extra GPU performance?

Given that the GPU is a mid-range card, you're fine with PCIe 2.0.

Now if you had a a GTX 1080, you'd want that PCIe 3.0.

Thanks, do you think this will give me issues in relatively high end games such as Black Ops 3 or Overwatch?

You'll be fine. Overwatch runs for me @ 60fps on ultra with a GTX 660 + i7-950 @ 1080.

No need for you to upgrade your CPU.
