I've been looking at ways to get data out of my computer onto a RAID enclosure, and the 20Gb/s number on this Thunderbolt 2 AIC card looks good. However, I'm trying to figure out if there is a catch.

I am running an ASRock Z97 OC Formula, with EVGA GTX 780 cards in SLI. I am big into gaming, multi tasking, media editing, etc.

I understand that this AIC card connects to the PCIE6 slot on this motherboard, which is a 2.0x16 connection. There is a cable that goes to the motherboard header, and then one more than I don't understand--the display port cable that runs from the graphics card into the Thunderbolt card. The only reason I could see the need for this, is additional bandwidth (throughput?) by utilizing another lane. My concern is that I'm going to see fps and performance drops by sapping bandwidth from my graphics cards in the name of other storage data transfer.

Can someone please explain to me what the purpose of this display port connection to the graphics card is, and if it will in fact rob my system of graphics power?

Thanks
