8Mhs (per R9 280X) is netting me about 85 coins a day, is this what everyone else is getting? With the rise in network hashrate coins/day has dropped from 115 to 85 in the past 3 days.. Not sure if this is good or bad

I averaged 100 per 280x for past 24 hours. (~9.2MH/s per 280x)
So your number sounds just spot on with 15% less hash rate.
