How much do these hash at each? Are they not 350-450 each?

540 Kh/s combined under clocked 795 core 1gb mem version (+-270 Kh/s per card).

540 combined or each? I did buy one of these and it cmae today and it mining @ 300khs with no config tweaks other than i-13

I have 2x Asus 7850 1Gb versions "--thread-concurrency 5120 -I 14 -w 256 --gpu-engine 795 --gpu-memclock 1200" script @ 540 Kh/s, max temp 71c
Purchased these for a friends PC build who then changed his mind, so I put these in my everyday PC that runs 24/7 anyway. They work great for what they are. I'm not pushing them to hard as I need to be able to use the machine, @ -I 14 there is no impact to daily use, some live video streams don't run. I did get these up to 600 Kh/s without to much trouble, but the machine is then unusable for anything else.
4 of these would make a decent miner for the money, with relatively low power usage with some tweaking.

Link please? I can't find this. And this is a no-brainer to buy. You couldn't ignore it.
It's probably expired would be my guess.

Two completely different mining topics. I have 2 of those cubes and also just started building a rig. I snagged a 7970 and R9 270 so far, along with all the other needed parts 
Should be here Monday.
What mobo and psu were you planning on running? If the cards are $586, your looking closer to the $900 mark to get everything else.

You might as well buy a miner from China for that money, and get 38ghs

I used them. The 7850 is awesome go for it! I used twin fan 2Gb models and they were always cool and quiet.
Two are as powerful as a 7970 (2x1024 Stream processors) but it's only 2x 6-pin (2x75W) so are way lower power consumption!
Only the 7990 2nd Ed, (2x 8Pin) can touch them on power efficiency.

That's not how you measure a card's power efficiency. You calculate the delta between idle and load states using a kill-a-watt and divide the hashrate by that delta (assuming the idles states of all cards will be more or less within 5 watts).
The higher end cards are usually more efficient since they have one less PCB to power and less memory.
Undervolting and ambient temps would play a bigger factor than anything else.
Thinking about buying 4 of them.
$586 for 4x with shipping(rebate only works on 1 per address)
~2.8khs/$
If you did extra work to get rebate on 4x it would be $496 for 4
3.2khs/$
Best I think you can get atm?
Could probably have a 1600khs rig for ~700-900
Is that worth it?

Might be worth it to the average or beginner, but probably not for someone who does this as a living. I generally don't stray far from the 7950/280X realm as I can still get them in bulk for MSRP. It's not that the value isn't there, I just have to deal with that many more rigs to get the same hashrate and also unloading the items when the time comes is more of a hassle if you have older gen cards and more of them. If this is your first rig, that's not a bad starting point.
Would you mind sharing where you are getting them from?

the funny thing is, not long ago 7950's were $180. I have one in my gaming desktop. Didn't buy it for mining and had no clue about mining. I check newegg and they are like $500 now......... wtf. Litecoin made gfx card price go up so high. Well, for AMD cards that is. It would just be a side rig as a hobby. I have a job and get my 4 0hrs with decent pay as IT analyst. I was thinking to rent out $20-25 a day, wont take long at all to get money back, then rest is profit.
