Question about MB

[mongerer]

If i picked up a MB with 3 PCI 2.0 x16 slots, can one be used for a pci-e x8 RAID controller and the other two for a multi-gpu setup? planning on getting a ARC-1210. Any suggestions or recommendations?

Orrrr are there any pci-e x1 raid controllers that are recommended for a setup with only 2 pci 2.0 slots?

Yes it's possible to that.

There are five (not counting the open-box) motherboards, at least on newegg, that offer 3 x PCI-E 2.0 slots:

However, two of them are out of stock. One of the remaining three uses very expensive DDR3 RAM and is based on Intel chipsets.. The remaining two are based on Nvidia chipsets.

AFAIK, there aren't any PCI-E x1 hardware RAID controllers. Most of them are fakeRAID solutions with support for only RAID 1 or 0.
