I guess this thread is an opportunity to summarize the top miners (>10 Ghash/s) who have publicly discussed their setup:
o vladimir: ~40 Ghash/s (source: his comment). Has said publicly he uses a bunch of Radeon HD 5970, hosted in UK datacenter(s). He sells mining contracts.
o ArtForz: 38 Ghash/s (source: IRC #bitcoin-dev #bitcoin-mining). Half of his mining power (~19 Ghash/s) is provided by 28 x HD 5970 + few other ATI GPUs. The other half (19.2 Ghash/s) is provided by 96 structured ASICs, from his own design. Claims 200 Mhash/s per chip at about 10W each. Pictures of his GPUs: http://bayimg.com/eABDfaAdd http://bayimg.com/KAAeaaAdp
o Myself: 15 Ghash/s: bunch of HD 5970, plus a few HD 6990. Open-air motherboards on rack shelves (kind of like Facebook's OpenCompute servers). Most of my nodes look like this: http://blog.zorinaq.com/?e=47
I don't know who the 4th guy with >10 Ghash/s could be.
Edit: this is gutsi with 14 Ghash/s with 5850, 5870, and 5970 cards.

Was mining for 2 days... Lucky?
go buy a lottery ticket.

seriously though, is this legit? Did it mature? Been running 1.1 GH/s the past 2 days straight with no luck yet!

So far my has power is 633 Mhash/s (radeon 5970) but soon I'm going to add two 5870s so that should bump it up quite a bit..dunno maybe in the 1.3 gigahash range?
Yes. A 5970 is basically two 5870's in one card.
Sort of yes and no. The majority of 5970 are not the 100% equivalent of two 5870s in Crossfire. The card that I have though (5970) has two fully fledged 5870 cores running at 850 so that card at least IS the equivalent of two 5870s but like I said the majority of cards are not like this.
Either way I really worry about whether even with the addition of two 5870s I'll be able to make a profit vs the cost of electricity. I pay $0.09 per kWh.

1.7g from a crazy assortment of 5830's, 50's, 70's and one 6950 coming this week. I may sell off some of the 5830's to replace them with 5870's if I can find them at a good price.
Best Buy isn't the usual suspect for cheap GPU hardware, but I went over there on a whim and they had AMD/ATI cards on an end cap at significantly reduced prices. No 6900 series cards though, so I left. Overnighted a 6970 from Amazon (Prime) and it was still a little cheaper than Best Buy before tax, but the lower end 6800 series I think were priced to sell. Just in case you want to browse.

yes, VERY lucky.All bets are off until credited

1 gHash/sec roughly in my current setups. 1.35 gHash/sec this afternoon with my next 5870. Considering building another new rig for a second pair of 5870s. It seems that it's cheaper to build 2 rigs with 2 5870s each rather than a single quad 5870 setup. The motherboard, case, and power supply for a quad 5870 setup are pretty pricey, not to mention possible cooling issues.

My sig is surprisingly accurate (Average speed in last 30 minutes) edit: normally 7 Mh/s, stupid sig 
expansion plans:
A single 5870 in my current machine could break even in 6 months (that's less electricity and internet)
and dual 5870s in a new system would take about the same.
Just have to keep my eyes peeled for a cheap 5970
