I'm thinking about maybe the 5070s.  The seem to be a good price point.  I started with a 6870 in my existing PC but I'm wondering if that's not the best in terms of hash/dollar performance.  The other thing I'm considering is if it would be smart to go with 6990s, since even though it may not be the best hash/dollar, the fact that I could put 4 into a single dedicated, purpose-built mining rig might be smart, as opposed to having to build two separate rigs to get that sort of hash rate.

And another thing - any problems running 4 video cards with Windows?  I thought I'd read somewhere that it's not supported with Windows but is with Linux... seems like this wouldn't be the case, but can someone validate this statement?

All thoughts are very appreciated.

Thanks,
Jeff

hash/dollar is not your problem.
Think about hash/watt.
You can buy and sell your card(s), but you have to pay for electricity.

I think Windows is not interested in how many cards you have.

How about linux virtualization?

I'd like to do that because some nontrivial fine motor disability makes me use voice recognition software.

I use cygwin all the time to maintain remote servers.

I just wonder if I'll get the eight GPU benefit of linux in virtualization.

Sorry to hijack the thread.

Like what I posted?

If you're talking about a Linux virtual machine, no. The OS and drivers must have direct access to the video cards, not through a virtualization layer.

Thank you very much.  :-) So I will work through SSH.

That's a better situation anyway.  Debian Lenny or Ubuntu.  No GUI.  Straight mining rig.

I LoL'd at Windows Mining Machine. Smiley

Sorry, know that's not helpful, but really take the time to learn the *nix ropes and you'll thank yourself later.

i have not seen any difference in mhash between optimized minersoftware/kernel on windows to the same machine on linux.

So any recomendations for which video cards to use?

Thanks for the thoughts on the Linux based mining.  However, I'm going to stick with Windows for now, since I just want to get some serious hash rate going ASAP.

Cheers,
Jeff
