Please help me with overclocking and RAM/MBoard compatibility

I am having trouble understanding all this stuff about overclocking RAM and motherboards that support it.
For my new gaming PC i can buy either:
• DIMM DDR3 2x8GB 2400MHz Kingston HyperX Savage CL11
• DIMM DDR3 2x8GB 1866MHz Kingston HyperX Savage CL9
For my new motherboard i can choose between:
• LGA1150 Z97 ASUS SABERTOOTH Z97 MARK 2
• LGA1150 Z97 ASUS Z97-PRO GAMER
• LGA1150 Z97 MAXIMUS VII RANGER
• LGA1150 Z97 ASUS Z97-AR
My CPU will be Intel i7-4790K and my PSU is a 750w Seasonic SS-750AM2, GPU is Nvidia GTX 980.
I understand that CL9 is better than CL11, but the entire overclocking thing baffles me.

What really confuses me is the following:
1. Sabertooth motherboard does not seem to support 2400MHz RAM - but it does support 1866MHz RAM without overclocking, or am i mistaken?
2. The other 3 mother boards support up to 3000+MHz RAM, but they do not support 1866MHz RAM without overclocking?
3. I do not understand how RAM overclocking works, do i sacrifice my CPU performance (or something else) when i overclock my RAM to 2400MHz?
4. If the 2400MHz RAM is left to work at only 1866 MHz, does it still have CL11 - or does the latency drop to CL9 since it runs on 1866MHz?
5. Which motherboard would be the best choice if i want to run a 1866MHz RAM at CL9?
6. Which motherboard would be the best choice if i want to run a 2400MHZ RAM at CL11?
I am not able to understand which RAM should i pair up with motherboard for maximum performance?
The prices are very similar, so money is not the problem here - i just don't understand which RAM+Motherboard would give the best performance in games like Battlefield 4 (64 multiplayer).

(side question): what is better for a single Nvidia GTX 980 GPU, a PCI (32-bit) slot or a PCI-Express 16x slot?

I Can't tell you for the OC in RAM since i don't know a whole heck of a lot and am trying to learn about OC for myself ATM but i do know that you'll want to put your 980 in the PCIe x16 slot, i don't think it will even fit in a regular PCI slot so definitely do not try to force it just put it in the x16 slot I'd say maybe also look into MSI motherboards because they come with software to basically let you OC your entire PC (at least thats what my friend that has an MSI mobo says) because MSI command center is not available to anyone unless they have an MSI mobo so this might be worth looking into for your mobo/ RAM situation might make all of that a little bit easier for you and my friend has the MSI X99 or 97 whichever it is and it not...
