It's something you might want to look into as far as the 7970 is concerned.
Very impressive on the 780Ti's though, congratulations.
Yeah, I SHOULD be getting more with my 7970, but as with the other people that own the crappy XFX DD 7970s, they don't overvolt or OC well. I have to run cgminer with a single CPU thread to get the best performance. Using 2 threads which some people suggest, gets me like 400 kh/s. 1 thread with more concurrency gets me around 550 kh/s. It should be far better, but after 2 hours of trying about 10 different settings, and the fact that the GPU is a terrible OC'er, I gave up and within 5 minutes, each one of my 780 Ti's (which are Classifieds, and good overclockers, were destroying my 7970.
I've got 3 more 780 Ti's, that OC as well or better than these two, but are on air instead of water, as well as a 780 Classified on air, and a 5870 on water that needs to be added.
I tried reviving some old Q6600 rigs to use as the base station for the GPUs, but they've been collecting dust too long and didn't want to start up for me. One wouldn't give me a video signal, the other gave me a POST error code on the LED display, and hung at the BIOS screen.
So yeah, I'll be picking up a cheap AMD mobo with 4-5 PCI-e slots, and using that as the base station, with some PCIe risers.
Given the amount of KH/s I can achieve with the 780 Ti's, they aren't much worse of a per watt cost per kh/s than the 7950/7970, which since I own them already, it's' much better than buying a bunch of Tahiti cards off of people that have been abused for years off of Ebay. lol
I was going to sell my GK110 cards, but I figure I can make a few bucks off of them mining DOGE, Galaxycoin, or whatever happens to be trending over the next few weeks.
I've already mined about 30k DOGE since yesterday, so it's pretty decent with Nvidia cards.
The latest cudaminer release gave us Nvidia owners a fighting chance. No longer is it an AMD only race.
It's a shame however, because I used to own about 7 7970s before swapping them for GK104, and then GK110.
