RAID controllers: PCIe 2.0 vs PCIe 3.0

[Permutation]

Howdies and hello...

I'm either modifying a current rig or building a new one to do Adobe Premier editing and intend to have a 3 drive (minimum) RAID 5 array installed as my source disk (D). I've looked at prices for controller cards and noticed quite a bit of difference between PCIe 2.0 cards and the newer 3.0 versions. My first question: is the difference worth it? Second question: recommendations/opinions for a good card (and if money were no object I'd buy an Areca card and we wouldn't be having this conversation).

Thanks.

Will you be using very fast SSDs? Hard disks can't bottleneck PCIe 2.0.

I'll be using an SSD on C, but not D. So, you're response was very helpful as I'll be able to save a buck or two. Thanks!

You can run several 15K RPM drives on a PCIe x8 controller, but very few SSDs.
