i just picked up a couple. and the cheapest 5850s are only twenty bucks less:

MicroCenter is better than NewEgg - and i have one just down the road...

The same 5850 is $40 cheaper on newegg with rebate.

The coolers on those cards are nice but they don't vent out of the case, they just pass they heat issue from the card to the case.

The reference ones are better.

5850s are not as efficient as 5870s. Less stream processors is my guess as to why. You can get four 5870s on one PSU, no problem.

5850s are significantly cheaper to buy though.

You would save money on the MB if you went with less 5870's.

For me the 5870 is the sweet spot. I would love to have a 5970 but I never run into them cheap.

Where can you get 5870's for a reasonable price though? Everywhere I'm finding them they're 300+

My question is does having cards in the 8x and 4x slots decrease your mining throughput?

No. PCIe x1 is perfectly fine for mining

So in regards to PCI-E 16x slots.

Most boards have 2x 16x operating at 16x and 16x or 16x and 8x or 8x and 8x.

Even the high end ones with 4 slots are usually only 16x 16x 8x 4x

My question is does having cards in the 8x and 4x slots decrease your mining throughput?

So I'm new here, but just wanted to say Hi!

My question is, are there any confirmed 4 card systems out there?

What motherboards are they using? Cards and Power Supplies?

I'm looking at a 4 card system and right now I think 5850's are the most economical because I'm pretty sure I can get 4 of them on one PSU. They're relatively energy efficient and the Cost/MHash is incredibly low.

Apologies if I'm not scouring the forums well enough before asking this. TONS of good information here.

Oh, and is there a thread on vladimir's setup anywhere?

Thanks!

Jorge

You might be interested in some set-up like this one.

P.S. dust seems to have it bookmarked while I was googling for "whitepixel" Cheesy

Are there people who have built custom boxes to put 4 high end cards on one motherboard? 6990's or 5970's

The cooling issue and the Cost issue is why I was thinking the 5850's would be better.

The 5870 is not as readily available, and when it is the price is between 2 and 3 times higher than the 5850's.

Keep in mind putting 4 cards on a motherboard results in the cards flush against each other. 5870s will throttle if not cooled sufficiently. You may want to consider building 2 dual card setups with cheaper PSUs and motherboards.
