dich 12.3 and go back to 12.1.
Thats indeed strange, I have a Asus HD7850 @1300 mhz core, and it gets around 350 mh/s...
Try it with a game like Battlefield 3, it should run 50-60fps on stock clocks ultra 1080p with the lastest beta drivers. (My OC gets me 70-80fps). If that is 30 or lower, its broken..

Use GPU-z and check your clockspeeds and temperatures while mining, as well as your usage. Second tab.
Ya 44Mh/s means somethings wrong. I would do as you suggested and re-install the drivers. Or just go ahead and update to the newest 13.1 drivers. What mining software are you using?
And rather than moving to the mining subforum, there's a mining support subforum that's for stuff just like this.

Use the hardware subforum. You'll get more views there.
I had my Sapphire 7850 2GB card RMA'd and they sent me the exact same model card.
Before I would get 270 Mhash on slush's pool. Now I'm getting 44 Mhash. Any idea why this is?
Do I need to uninstall the drivers and reinstall? Even though it's the same model (but not the exact same card of course) ?

ya i'd try that...if not then maybe you got a dud card back...those mh/s for a gpu is sad..are you using same miner? same everything? it should be doing what the old one was doing...
