Anyone have any experience with Unity Electronics, the vendor that this comes from?

Also, if you go to Unity Electronics website and search for the card, the same one comes up on there for $599. Why $100 more to buy it direct from Unity as opposed to buying it from Unity via Buy.com?

Obviously a new in box 5970 is a good buy at $489 but I just have to be skeptical of any vendor I'm unfamiliar with.

buy with your credit card so in case anything happens, you can dispute it.

Yes, I ordered 2 from them a while back and got them just fine.  Very good job on packaging too.  not like the crappy job newegg did on these 5970s

We had a different thread with the subject.. but I can't find it.

I wont say that 800 is easy just yet. 

I have about 20 5870, and I get about 420 out of them at 940. 

I just received 3 of these 5970's (finally) got them amazon last week.  I successfully got them installed on a msi gd70 with a silverstone 1200 running linuxcoin.  I crashed the rig a few times overclocking.  I now have them running stable at 725/400.  will burn them in for a day or so and try to overclock them again.
I guess what I am saying is dont expect them to act like 2 5870's packed into 1 card.

Running 3 5970's (6 gpus) on a 1200W psu and overclocking them might be pushing the power supply a bit too far.

Even if it has enough juice, you will need ~80 amps on the +12V rails (or rail) just to keep them running at full load.

Top PSUs are rated for quad crossfire compliance at the most.
They don't even make specifications for 6-8 gpu setups. However I find thermaltake 1500W psus able to run even three 6990's at stock.

Thermaltake 1500w is for 230v AC.
the 1350w model is for 115v AC.
Any "good" 1200w model should run what you want. Antec, corsair, silverstone, enermax, thermaltake. Probably missing some.

80 amps....  is that right?
I was just adding up the watts.  my psu is rated to peak at 1300.  run 1200 24/7.  

each card should pull about 375    * 3 1050.  no hard drive or any fans.  

I will let them run at stock core clock for a day or so then play with them again.  

I must say they cool better then I expected.  I have the fan at 60% and it blows the heat out the front of the card :)

edit:  i couldn't wait.....  bumped them up to 775/440 while they were running
