Any GPU and motherboard made in the last 7 years is compatible with one another.
Now the CPU in that 970a chipset board is going to bottleneck a 980.
If the CPU is an fx-8350 then it will bottleneck a little.
If the cpu is an fx-6300 then even a 970 will be bottlenecked. Getting a 980 would not even gain you much of anything over the 970
