The bottlenecks are between the CPU and the GPU. You have a seriously fast CPU so you should be OK no matter what GPU you have. No need to worry. The 970 boards are just not as overclock-able as the 990 boards. You can still OC with a 970 board, just not as much as with a 990.
What model 970 MB did you buy? If it is made by either asrock or MSI, just forget about it. if you got ASUS M5A97 EVO or PRO, or GA-970A-UD3, then you may use the fx8350 and 2x r9 280x with the right PSU.

You are only gonna get X16 speed with one or two PCIe X16 slots no matter what their default speed is. With one, two or more GPU's I doubt that you will ever get close to using all the bandwidth (X16). Bottlenecks are the least of your worries especially with your 8350.
If I have already bought a 970 motherboard for my 8350 and 2x r9 280x's should I be expecting bottlenecks from the motherboard?
Hi Dougiedoug.. sorry to hijack your post, but i have the same set up ( ga-970a-ds3p and 2x msi r9 280x) but keep getting " device disabled error code 43" on my second gpu, did you get this?
