Pci-e 1x vs 16x for GPUs? Help please

I've got almost all of the details for my new rig sorted out except for the motherboard because I have a question regarding it. My understanding is that 1x (pci) means it has one data lane and 16x means it has 16 data lanes. I am using 7950 cards, FYI. When purchasing a motherboard, does it matter if the 7950 cards are attached to a 1x or a 16x pci? What I really mean is: will a 7950 card hooked up to a 1x pci have a lower hash rate than one hooked up to a 16x pci? Or does it not matter which type of pci the cards are attached to?
Thanks

According to NIST and ECRYPT II, the cryptographic algorithms used in Bitcoin are expected to be strong until at least 2030. (After that, it will not be too difficult to transition to different algorithms.)

Biggest difference will be on risers if u need powered or not. Also its kind of nice to have a longer one but not a necessary thing.

If you mine with up to 3 GPUs, you don't need to have a powered risers. Also, if risers are 19cm - they are long enough for most rigs.
