6990s were sold out before bitcoin became a craze. They were a limited production line top end card. They're also a terrible $/hash buy for mining.

Exactly. These are gaming cards and probably a very, very small minority has been purchased for distributed computing.

Not to mention they cost $700 to $800 for about 600-700mhash/s, you can get two radeon 5870's for $300-$400 bucks at the cheapest & achieve the same or better.

Wha?  I get 850 mhash/sec on stock voltage on my 6990.  It's overclocked to 990 on both GPUs.  I could probably hit 1050 easy.  

And the point of the 6990 should be to have an awesome gaming rig AND hash.  But I don't think that's the case for a whole of people.

Either you got very lucky or you're full of s**t. The average 6990 goes nowhere near 990Mhz let alone 1050. Not to mention when overclocked the average 5870 (not a super special golden overclocker) can do 420MHash/sec. They game pretty well too surprisingly (for the same money you will probably get even better fps, though lots more noise and heat).

Ah, I wasn't aware that they are already sold out. Damn, things change quick.
I have a scandinavian computer-hardware/accessories supplier that has them in stock.
Komplett.se (Swedish site)

But I hardly believe they ship abroad. The company itself is located in Norway but they have business in Sweden as well.

I probably agree with you both, if I had my thinking hat on.
I picked up a couple of 6990 and a pretty much new rig with 'free' bitcoins I got last year and didn't realize were worth anything (they have over doubled in value since I flogged them - but I'm trying to ignore that).

Justification for the 6990 is that in the near-ish future I know that difficulty is going to go through the roof, and mining will go back to being something you do in the background (which was always the intention I think of bitcoin). So I'll flog on of my 6990 off - and I'll pretty much get my money back. Buying an older series card is definitely the best bet for mining, but I'm a little dubious of anybody who does so currently ever breaking even. Much nicer to think of it as a free games machine Smiley

Probably 6870s. They're plentiful, they go on sale a lot, they hash a little worse than a 5850 and use less power. They're not as efficient for your dollar, but such is life. If you can find one on sale for $150 - $160 it's not a bad deal. They do about 300MHash last I heard, which is about 1.875Mhash/$. Not great, not awful (for comparison 5830s do about 2.75 MHash/$, and 6990s do about 1.14Mhash/$)

Plenty of 6990s available here in Australia at MSY.  Not quite sold out everywhere (or bitcoin hasn't caught on here).

i'm currently using 6950's w/ shaders unlocked and i'm quite happy with them. @ 840mhz they're getting avg 680 Mhash (2 cards). i just placed an order for 2 more. if you can find a reference 6950 for 250 i suggest you buy it. i know xfx' version has all but sold out, and currently ~350-450 on amazon. newegg still has a couple HIS and MSI models, but idk how long they'll last.

It's the best, unless maybe you are living somewhere with really expensive electricity. Or you only have one available slot on your PC and do not want to get a new one.

With some risers it can fit six!

Just looking at it, it looks like it *could* fit 3, but the middle one would be wedged between the other two.

well couldn't you use (from left to right) blue slot 1,3,4 and not use #2 since these cards are double slot?

Not so fast. Gigabyte 5870SO model kicks asses 24/7 with its 950MHz for 410-425Mhash/s depending on the miner app, but dual-fan cooling system is ... noisy. Jumps between 190 and 200W power consumption , but I'm lazy to check that with lowered memory clock (around 350MHz for stability purposes).

I have a Gigabyte 5870OC (same cooler, but with a small 20MHz OC). Been running it at 960MHz with the fan at 60%, and I don't find it very noisy. Just ordered a 5850 with the same cooler (my sense of geek aesthetics demands that I have matching hardware in my desktop system...  Tongue), so I guess I'll find out how two of them sound together in a couple of days.

it's one of the cheapest up front, but it hogs electricity. even if you oc it to 996 it still gets .85 mh/w

at stock it looks like it is 245 Mhash/s and under full load 243 w (http://www.bit-tech.net/hardware/graphics/2010/03/22/xfx-radeon-hd-5830-1gb-review/7)

so, what is the Mhash/s and power consumption overclocked? the above link says 263 w @ 930/1200

As I said, mining is now constrained by the supply of video cards.   I had now two orders canceled by suppliers who said in stock then went to out of stock.

hrm. this site i saw said it was much higher, 359w at load. http://www.techspot.com/review/249-ati-radeon-hd-5830/page11.html

according to http://melanarchy.info/bitcoin/ it gets 307

So many misconceptions about power:

Those reviews are calculating Total system power draw from the wall. Not the draw of the card from the PSU.
