it says my board has the 970 chipset and the 970 is not listed on that chart ??

It supports up to Quad Crossfire . Realistically it supports two GPU crossfire.

Expansion Slots
1 x PCIe 2.0 x16 (blue)
1 x PCIe 2.0 x16 (x4 mode, black)
2 x PCIe 2.0 x1
2 x PCI

You can crossfire any TWO GPUs up to the R9 290 or K6000 without a problem.

The theoretical bottleneck of your mobo is the: "1 x PCIe 2.0 x16 (x4 mode, black) " , but the bandwidth is still 2Gb/s, which only the very top of the line GPUs can reach, and even then, most top of the line GPUs won't actually use/demand/need that much bandwidth in real life useage.

thanks alot man for clearing that up
