AMD power consumption and Nvidia's efficiency to mine, honest opinion needed

[malekbaba]

i am upgrading my rig
I am trying to get a PSU

Will it handle 2/3 AMD card?

Currently I am mining ETH. But it will not last for ever. So currently 7950/7970 are good card for mining ETH. Do you guys think that 7970 will be a better option for future mining ? As electricity bill is a matter of consideration, if I want to upgrade my rig, should I buy 7970/R9280x cards or should buy newer cards?

Or I should buy nvidia's?

I am confused again. Help me please

The cards which consume less electricity are usually very expensive.

That PSU should work since it has 6 PCIe connectors, each of your 7950 use like 150watts or so.

so do you suggest to buy old AMD ? Will they be good for future mining? i prefer 7950/7970 cards for mining in future

truth is if want to mine now must use ASIC. cheaper to buy ant or zeus.

Yes buy 2nd hand used from Craigslist or Kijiji.

Most likely ETH mining will be profitable for only another month or so.
