3xGigabyte 7970ocs, averaging 600-700mhs. 2xGigabytes pulling 660 watts at the wall. I'm trying CK's settings from this post, https://bitcointalksearch.org/topic/linux-cgminer-quad-hd7970-system-up-88056, stating the cgminer is pretty much tuned default for 7970s. Reminds me of the old days of trying to eek out a little more mhz from cpus, and finally realizing oc'ing is a pain. I'm taking baby steps up from default settings.
Good luck and fortunes all!

Currently running 2 x XFX 7950, on Asus CF board and AMD A4 CPU all under clocked (GPU700MHz, MEM 600MHz) and under volts(0.950V) @734 Mhash/s, CGminer.
Total system power draw @734Mhash/s = 330Watts
Default clocks - 850Mhash/s = 450Watts
Flat out but stable, temps 80C, fans screaming, @1084Mhash/s one card 1150MHz other 1050MHz = 675Watts

I've got nothing (story of my life)...
I get 47mh of one and 14mh of the other. both built using NVidia (if only i'd known).
anyway, just happy to help secure the network, my wallet has the block chain and i'm open to incoming connections to help secure transactions (it all helps, right?)

Sapphire HD 5770 with core at 950 and mem at 300 i get a stable 204 MH/s when mining bitcoins with the following settings for cgminer:
-I d --thread-concurrency 3200 --auto-fan --temp-overheat 76 --temp-target 75
I realise I could probably squeeze out some more if i set a different value for -I but this way i can mine and still comfortably use my pc.
When mining litecoins I can get up to something like 190 kH/s but i'm not really sure to be honest because that involves setting -I to 18 which makes the pc unusable for other tasks so I quickly gave up on that. For the moment i'm using -I 12 which gives me a hashrate of 155 kH/s with the core and mem on the stock of 850 and 1200 respectively.

Hashrate : 100Mhash/s on tower 1, running Geforce 670, 280 Mhash/s on tower 2, radeon5850. It's what I have right now, hoping to build a custom rig or pick up some ASICs soon. Wish I'd paid more attention earlier.

7950 + 7970 = 1300Kh/s.
I'm running 1 X 5850 at core 775 Mhz and memory 1125 Mhz Fan at 90% and max temp of 80°.
I,m gettin an average of 300 MH/s.
My mother board supports only 1 16x pci, and using two card it would go down to 16x and 4x. Would that make a difference using two 5850 for mining?

I'm running 2x HD 5850's
One is clocked at 1.2V and 975MHz core = 385 MH/s
The other is stock voltage and 900MHz core = 360 MH/s

2 6950s in a tower case.
AMD Phenom II X4 970.
850 watt PS. The whole system typically draws 450 watts.
I use this box for other misc stuff too.
The two 6950s typically get about 620 Mhps total with bitminter and I run them at 80 C. If I max their clock speed they climb to ~700 Mhps but get too hot - I have some beefier after-market GPU cooling fans on order.
Eventually I'll pick up a couple more cards and figure out how PCI-e extender cables / risers work (think I need powered risers, not sure). Once I do I'll get rid of my case, get some conventional fans, and overclock everything.

currently just toying around with my older gaming rig to try my hat at mining [thus newbie]
EVGA GeForce GTX 560Ti [stock] hashes at anywhere from 65-90 MH/s
That's using GUIMiner -> rpcminer-cuda.exe
Does anyone know if I can mine LTC using CUDA or OpenCL? I tried to get it rolling last night with no luck. This was while slush's pool was down so I figured it was a good time to give Litecoin a try since I will likely be moving to that with a GPU setup in the near future.
Thanks have a great afternoon

Your 7750 is running a little low. You don't need a good CPU to mine, and you should run your memclock at 300MHz to save on temperature.

anyone who can build and sell a 1gh/s asic miner. pm me.
An ASIC miner at 1GH/s is practically worthless. With the speeds you can achieve with ASIC builds, you could do better than 1GH/s. However, you'll be lucky to find anyone who will have a DIY built soon. I'm only speculating on parts now while designing my own FPGA. You're going to be waiting a while.
I also recommend that if you want a ASIC DIY build, you don't ask in the Newbie section. Most people who are posting in the Newbie section are actually new to mining, and many of them don't have the experience enough to build an ASIC rig (I'm assuming).
I have 3 x 7950. Not over clocked they hash at 480Mh/s each. I run them fully overclocked and each is hashing between 600-620 MH/s at 75-80C which is not bad. Avarage hash rate is 1740 Mh/s from all 3 cards. GPU clock at 1200Mhz and ram 1500Mhz also added 12% on power. I could wack poer to +20% but my temp rise to 85-80C. In my opinion 7950s are best cards if you take the price and what they can do overclocked.
385GH/s waiting for ASIC with crossed fingers!! 
What do you need an ASIC for with 385 GH/s?
Ati 5870 Vapor-X, Core: 900mhz, Mem: 600mhz, 385GH/s waiting for ASIC with crossed fingers!!
Has anyone considering stringing together an array of 6670s at $65 a piece (newegg)? They get over 100 MH/s and I'm sure some tweaking could be done...
I've got a few rigs I use while I am searching for cheap parts and designing an FPGA:
Desktop/Server/Gaming (full specs):
MSI Big Bang XPower II
Intel i7 3930k 6 core 3.2GHz (OC'ed to 4.0GHz stable)
32GB (8x4GB) Kingston HyperX DDR3 1600MHz
EVGA GeForce GTX 480
500GB VelociRaptor (OS)
4x3TB Western Digital Green 7200rpm
2x2TB Western Digital Green 7200rpm
- GTX 480 puts out ~190MH/s
3 Blade Servers (CPU):
Each is Dual Xeon, quad core
- Spits out about 50Mh/s per machine
Mining Computer 1:
Crappy motherboard, 4GB RAM and AMD Athlon x2
AMD Radeon 5770
- Averages ~230MH/s
Mining Computer 2:
Crappy motherboard, 4GB RAM and AMD Phenom 940
AMD Radeon 6870
- Averages ~300MH/s
So currently given my thrown together lot, I can produce around 870MH/s all together, and I don't use very much electricity.

I'm using these settings on my 7970:
cgminer.exe -w 256 --thread-concurrency 28672 --gpu-engine 1120 --gpu-memclock 1780 -I 13 --auto-fan --scrypt
and I get 600 khs. I've tried all sorts of combinations. Is that really the best it can do or am I missing something?

LTC?
Yes, mining LTC (thus the --scrypt in the setting).
