7970 With Windows 7 64 Bit Pro

[Mir]

I am putting up a dedicated Machine for Mining.
I have two 7970 for this Job. They are in same machine but not in SLI mode.
What is the Best Version of Drivers.
and what is the best Mining Software ?
I have use Guiminer and it was easy.
Thanks

You don't need to crossfire your 7970s to mine (AMD uses crossfire, not SLI which is nVidia)

There is no "best" miner. If you like GUIMiner then use it.  Most people use CGMiner which requires a little bit of interface with command line.

Best driver depends on OS and what coin you are mining

I mean they are not in CrossFire Mode (Option is not enable)
I am going to mine BitCoin.
what is best Driver ? for Max Hasing ?

12.8 works fine for me.  Don't know about 13.x as I don't wanna have to clean up the mess if it's worse.

I have used both 13.1 and 13.3 beta 3 and I've not seen any noticeable differences in hash rate.  I change drivers mostly on one primary machine and don't often change anything on dedicated miners running stably.  Most of my uninstalling and reinstalling to different drivers revisions are from game stability, not sue to mining (good or bad).

Just my experiences.  Hope they help...
