Which is cheapest per Mhash/sec video card? without changing clock or voltage(to keep reliable)

Plus, Is there any solution to install more video card in one server box

I mean the server box like this

probably 6670 ultimate.
4x less shaders than 5870, but pack lot more per/watt and also not require fan-based cooler.
just plug 16x or 32x of this babies into PCI-e switch and FIRE it  ! Tongue

$/Mh/s, the 5830 is cheapest, at 49 cents.

that price is off.  Newegg has 5830 for $109, and they were on sale last week for $99/each so $.33/Mh/s

I can't buy it in PR.China, how much is the ship cost to Hongkong?

probably $20+ more.

It is pitch black. You are likely to be eaten by a grue.

the price may be off - but the cost/benefit ratios between all the cards is pretty good.  i run every one of the 58xx series in various miners, and i'm happy with the accuracy of the spreadsheet.

i also note that, in general, the 58xx series is overall the hands-down winner in $/Mh/s.  of course, once you get into a more practical calculation - i.e., Dollars/Mhash/sec/computer - the 5850 and 5870 turn out more competitive numbers, simply because the megahashage you can cram into a single box is higher.

meaning both 6950 and 5870 had same cost nowdays and give about 400Mh/s and 370MH/s respectively, while last one - consume nearly 1/4 more power ... ~$220 each.
but if you had access to you regional distributor store, you can get 68x0's for about $100. its about 170MH/s

6950 doing 400 and 5870 = 370m/h? vice versa maybe...
also your power estimates are off, the 6950 consumes 1/4th more than 5870...

or have I misunderstood something?

other way 'round.

5870 = 400 Mh/s

6950 = 370 Mh/s

Is it really so hard to open a spreadsheet and plug in the numbers that no one can do it themselves?  How many of these threads do we need?

yep.
until you:
1. "unlock" extra cores to turn 6950 to 6970[works on70% 6950's]
2. use phoenix miner.
3. mine w/o vectorisation w/256-worksize.

basicly 5870 is better card, except that 69x0's had Rendering back-end and more faster ram. but thats meaningful only for games/3D.
and had better power subsystem to support more hungry chip.
