Hello fellow miners!

First things first. Initially my current system is using Sapphire HD7850 for gaming + mining. Right now, im planning to sell my 7850 and buy a 7970 instead, to improve the mining hashrate, and of course gaming.

I do know that crossfirex is only do-able if both card are using the same HD7### Series, so obviously crossfirex 7850 and 7970 is definitely out of question.

Now im actually wonder, is it possible that i installed both card at the same time, in which 7970 acted as a primary card for display/gaming/mining, where as 7850 acted as a secondary card in which its only purpose is for mining? By doing this, i can get up to 700mhash/s++ and another 320mhash/s, bringing a total of 1ghash/s.

My motherboard is Asrock Z77 Extreme4 (2 slots of PCI-E x16), with a 650w PSU.

How about the PSU, do i need to upgrade it as well?

Thanks!

It should work just fine.  For you PSU, you might want to upgrade.  If it has 4 pcie connectors, you will be able to use both cards but it is bad to have your PSU running at full load all the time.
