I have read that 7970 is the best bang for the buck?
Input please?

I just noticed that the 7990 is out. Anyone have any experience with that card?

And your right, it is.
But, maybe ASIC is going to make them obsolete...

GPU mining is becoming less and less efficient due to rising difficulty levels. But yeah I'm thinking 7970 is good.

The only 7990s I've seen cost 900 dollars and probably won't be worth say 3 7950s for about the same cost. Can't really speak as to what is the best. You have to look around. I thought I was getting a good deal on a couple 6950s and ended up going with 3 6870s for the same price and more khash (I'm going for litecoin but the same principle applies)

I personally am using 6x 7950's for my mining rig.

Note: unless you can afford a lot of gpu's as an investment right now, maybe 7-8 gpu's or more, you probably shouldn't. Rising difficulty rates :/. Or try litecoin.

I'm quite much newbie to this mining but from what I've learned is that 7970 is pretty good.

It's rather simple, a 7970 should give you around 600 MH/s, with the right flags and bit of OC i think you should get 700-750MH/s atleast. That's decent

I just figure that I should get a 7970 or 7990 because if asic really does come out I can always sell the 7970 card on eBay or something probably for really close to what I paid for it. They seem to hold their value pretty well.

Cheapest 7970: Newegg $399 - 600MH/s average. Cheapest 7990: Newegg $899 - 1200MH/s average.
Depends how much you can invest. Note: there might not be product available now at those prices.

Agreed. I bought quite a fes last summer at $375, a rate I can't even find again today. They have held their value extremely well so far. Once the 8000 series comes out, it will be interesting to see, but it's still a very good card. I would be interested to see how well you can keep a 7990 cool, and if you could really get 2 x 7970 hashing rates. My understanding is it's basically twice the power at more than double to cost, so just doesn't make sense to me unless you only have a limited number of slots to fill and plenty pf PCI Express connectors available on a nice PSU. Per the post from LaudaM below, my 7970s are OCd to 1125 (anything beyond that, they get too unstable to be worth it), and I am between 690 - 695.

Obviously 7970 and 7990 are the best ones. But I personally like very cheap 6930, that could easily get 320, or even 350 Mh/s and cost 80-100$

I think any AMD 5830 is the best bang for the buck. Its hard to find them for sale anywhere.

From what I have been reading the 7950 is very efficient.

Oh I was comparing 7970 vs 7950.
I currently use 5870's, and they are not easy to find either.

The best card is the one you already own. Spending money on a GPU at this point is a losing proposition for *most*.
EDIT:
Expanding upon that... If you have $400 to spend, spend it on actual BTC. Then you will have ~4 BTC now. A $400 GPU will get you 4 BTC... when??? Diminishing returns every 2 weeks, plus electricity cost. Alternately, you could spend it on an ASIC mining contract, or actual ASIC hardware. Just not GPUs, if you're expecting to make a profit.
