Unfortunately, I do believe the 4870's are better performers with ROI. The most I can get out of the 8837's is 1200 h/s. That's with all eight mem carts and four dimms per in hemisphere mode. With the 4870's I was getting 1300 h/s with just two dimms per cart.
Kind of a bummer, actually.
EDIT: I'm running 32 threads per core and 128gb HugePages mem and am now getting almost 1300 h/s. Kinda' cool to be running that many threads.
2nd EDIT: Learning a lot about these things. E7 processors WILL NOT work on a system board that's not Revision OB or later. The one in my X7560 rig is OA. Dead in the water on that I guess. Found a complete chassis cheap and I made an even cheaper offer. Maybe they'll take it.....
