So.. I found a guy who's willing to part with a very lightly used Diamond HD 7970 for $200. I'm currently running a Sapphire Flex 6950 unlocked to 1536 shaders. I'm currently getting a stable 450 K/Hash. So.. a couple of questions. What kind of hashrate do you guys think I'd get from this particular 7970? Am I going to have problems trying to run both cards in the same rig at the the same time? Thanks.
