Can someone help me out with my miner really quickly?

I just set up a new rig with 2 7970's. I made the config file, and I'm not getting any hardware errors... but I'm not getting any accepted/rejected shares either. It keeps telling me "stratum from pool 0 detected new block", but no accepted/rejected shares. It's also telling me my hashrate is over 900 on each card which is probably too much for 7970's, since the most I see other people get is around 800. Also, my temps are staying in the 30's-40's and MSI Afterburner says my GPU is only being used at 45%... what am I doing wrong?
