So recently I just bought an Intel RAID Controller RS3DC040 and a MB GIGABYTE|GA-Z97MX-GAMING 5 MATX motherboard. I was told by Intel Support that the RAID controller would most likely not work on the motherboard I just got. I don't see why it wouldn't. It is a PCIe 3.0 8x RAID controller and the motherboard has a slot for it.
I'm strongly considering the deals on the 4970 as making this a decent time to upgrade. However, I'm wondering how the PCIe slot situation would work on a Z97 with a video card and some form of PCIe SSD in the long term. Would there be enough lanes on a motherboard to keep those both fully fed, and would there be any wrinkles in making that work that I'd have to keep aware of?
