Intel i5 4690k enough for 2 r9 390x's?

Will be building a gaming PC quite soon and I will probably be buying an r9 390x graphics card, then eventually upgrading to a second one. The CPU I am considering is the Intel i5 4690k. I was wondering if the CPU is going to be fast enough for the two graphics cards together, so as to not impede their performance.

Thanks for the help!

Yep.

You'll be fine, especially with DX12 launching soon here.

You will have no issues.

Unless you put in more pcie cards, then you will run out of lanes

depending a bit on the resolution you are playing at.
But basicly it should be fine.
