From the sounds of it though the 7970 just isn't worth it at all here. I'll talk then to the store see if I can swap them out.



Only have two PCIe slots and one is being used by my raid controller. Sadly I can't use both at at this point. That and the wife would kill me if I tried.


Thinking about that also but I'm having a hard time thinking about doing that when I don't see them really shipping many of them at this point and I'm not sure when I will get one. Even more so being they have had delay after delay and I believe they originally planned to start shipping sometime last year. I'm afraid of spending the money for them to only go belly up. For price to performance it wins but also limits what I can do from there with the hardware if bitcoin goes south as well.

I'm doing a bit of switching back and forth between litecoin/bitcoin/feathercoin with the card I have which is the 7870XT. Right now I manage to get around 518mh/s under bitcoin and under feathercoin or lightcoin I get around 340kh/s with my clocks at around 1200/1600.

As I'm still within the 30 day return window I'm wondering if it is worth it to upgrade instead to the 7950 or 7980. I've been trying to find information on either one but it seems most I find is regarding people running 2+ of each of them not running them solo. How much of a difference can I expect if I was to swap this card out for one of the above? This has to be done all air no liquid cooling or anything like that. It's not a dedicated mining rig either but I don't mind throwing a little extra money to a faster card if it makes it worthwhile.

What kind of hash rates do either of those cards manage to get once overclocked and what kind of clock speeds can I expect using them?
