24Kilo. I got some risers from China on ebay. About $7 to $8 each. Got some months ago and they work fine. Ordered some more a couple of weeks ago, keep forgetting to check the PO Box, they're probably sitting there waiting for me.

24Kilo: Just a thought, if you can put some space between the cards, they'll run cooler. Also, not sure if the GB's are similar to other R9/79xx cards, but the stock coolers push hot air mostly backward, and a little down and upward. That big fan I see on the back should be pulling air away from the cards. Might also benefit to put one in front of them, pushing cold air toward the rear of the cards.
Also, try it without the crossfire if you're not using it, you might not need it. I've never benefitted from it.

Vesper,
I need PCI-E risers but there are none in Australia and I have not been able to snag any from the USA. When I get risers I will separate the cards which will make a huge difference in cooling. The fans on each end of the cards push air into the cards in an attempt to get cool air into the 'top' card.
I am going to spend some time tweaking and tuning the Gigabyte Rev2's this afternoon.
Thanks!
Try having the front (near the DVI) fan push air onto the GPU, and the rear fan blow it away, and monitor your temps. I found that to be most useful, though I didn't have them as close so my situation might be different.
Try any of the chinese dealers? On the US Amazon site that's where I got some of mine, processed via Amazon but came from China. I'd send you some but I'm not sure it would save you money.
Also for anyone interested, I updated my Toxic post. I found out why the other motherboard provided lower output, it had to do with the scrypt kernel which came with cgminer 3.7.2.

Just snagged some ASRock 970-EX4 mobos for under retail. Whew!
If I don't use them all, I'll put them up here for the taking.
I might be interested. Keep us updated.

Vesper, what VRAM temps are your cards running at? I wonder what the upper limit is on those.
Never measured it before, if you have a link to a linux utility for it, I'll take a look. Better than stock I'd hope, as I put additional heatsinks on the VRM's. The TOXIC OEM VRM heatsinks look beefy.
http://openhardwaremonitor.org/ should work to monitor GPU temps and voltages, but it's been a while since I've used it.
I'll predicate my last message with, something mostly command-line which needs few, if any, dependencies, and isn't GUI based. lol.
24kilo: Nice man! Love the DIY.

805 nice. Can't wait.

This is veggie crate miner #3...
Specs -
Antec Truepower Classic 750W PSU
Gigabyte B75M-D3H motherboard
Intel Celeron G1620 2.7Ghz CPU
Patriot Signature 2GB 1333 DDR3 RAM
Hitachi 80GB hard drive
2 x Gigabyte GV-R928XOC-3GD-GA Rev 2.0 in CrossFire
Windows 7
cgminer 3.6.6
executing the following batch file -
cgminer --scrypt --gpu-map 1:0,0:1 --lookup-gap 2 --shaders 2048 --intensity 13 --worksize 256 -g 2 --auto-gpu --gpu-engine 350-1032,350-1036 --gpu-memclock 1500 --thread-concurrency 8192 --auto-fan --gpu-fan 85,75-85 --gpu-vddc 1.190 --temp-target 84 --temp-overheat 85 --temp-cutoff 90 --gpu-powertune 20 --expiry 10 --scan-time 5 --no-submit-stale --failover-only
GPU0 is running about 84C and GPU1 about 71C... remote desktop does not want to share GPU temps for some reason, thus missing from the screenshot.

What is the 'no-pool-disable' value?
Going from memory, I believe it prevents cgminer from permanently disabling a pool if it can't connect to it, instead it will try to connect in the future. I might be wrong though.

Vesper,
What is the 'no-pool-disable' value?
I am working on a rather long-winded post... just going to say... Fuse... I had a face-palm moment just like yours!!!

I run with the -g 2 switch as well, 24Kilo.

Vesper,
How many gpu threads are you running? Are you specifying an argument for '-g' or just letting it default? I have had no success at running at higher then TC 8192 with a value of '-g 2' on any of my cards.

I am not specifying anything in my config file for that, I believe it defaults to 2 but I might be wrong. Here's my config file on the mining rig with the Toxic (it's the middle card):
"intensity" : "19,20,20",
"worksize" : "256,256,256",
"kernel" : "scrypt,scrypt,scrypt",
"thread-concurrency" : "40960,24000,24000",
"api-port" : "4028",
"expiry" : "120",
"gpu-engine" : "1080,1160,1080",
"gpu-memclock" : "1500,1800,1500",
"gpu-powertune" : "20,20,20",
"temp-overheat":"87,87,87",
"temp-target":"50,50,50",
"log" : "5",
"no-pool-disable" : true,
"queue" : "1",
"scan-time" : "60",
"scrypt" : true,
"shares" : "0",
"kernel-path" : "/usr/local/bin"
Toxic is still going 805kh strong several hours later, no issues.

Finished doing my tests for the day. I'm going to let the card sit on the overclock for awhile and see how it goes. Need to swap the coolers out, and I'm waiting for motherboards to come in before I can put any other toxic cards to use.
Got mine from Amazon for $349, they're out of stock, but if you're willing to pay a premium, Newegg has them for $470.
Considering these seem flexible on hashrate, I don't think that premium price is too much, though I'd much rather them for $349..

Nice results, Vesper!
I got mine @ $440 on Newegg 2 weeks ago. Seems like they just keep bumping up the price when they come in stock. I'm honestly going to start sitting on Amazon all day trying to 1-click buy units like you do. $349 is a steal. Damn you, Vesper!
Easy Auto Refresh is a great browser plugin to do the refreshing for you
I waited 4 weeks for them to flash on my screen, I was hyper when I got them in my cart.Amazon doesn't mark-up which is nice, but with folks like me, their stock drops in moments. Newegg marks prices up and limits customer quantity, but this at least lets someone buy the card if they absolutely want to.
Happy with the hash results so far.

Vesper, those are some interesting results. I'm wondering why you aren't getting closer to 750kh in Linux. Tempted to get back on the linux train and try to get a nice working image for future rigs.
I might mess around with that today, now that the jackpot is taken care of.

I think it was something with the test system. When I popped it into my mining rack, KH shot up across the board. I'm logging the results now.

Yay I won something 
Fuse, keep an eye on my thread a few posts above, the Toxic is screaming right now.
