If i'm not wrong each card needs 2 (6PIN PCI-E) connectors but that psu has only 2 of those connectors , this mean that you can't have 2 GPUs.
You can always try and use molex-to-pci-e connectors but thats always risky as its not really clear which rail the power comes from and it goes against the designed usage. It works in some cases and not in others. To be safe its a good idea to keep the number of pci-e connectors in mind when choosing a PSU.

Well it only has 2 pci-e connectors while you need 4. But the 12v rail does have 408 Watts available which should be enough if you were to split them...
I would go for a PSU that comes with 4 pci-e connectors though, they are made to hold that kind of power and won't be maxed out all the time like this on would be.
At which point HW has devalued itself only by 20-25% worth.
Not very long.
I have been thinking that it's fair to consider a 40-50% resale value on all mining hardware purchased, more in cases of super high end things like 6990s.
Some pool-mates and I were talking today about the idea of colocating mining equipment. Considering things like electricity and cooling, it's a great idea.
Yep the high end videocards can probably be sold. But who is going to buy your Sempron 140, your pci-e extenders, your 2x650w psu or 1x1200w psu, your outdated motherboard and your 2gb low speed value ram?

Yep this is one of best flags for most 58xx miners. Aggression may vary though and this high will usually make your computer less responsive.
I've actually been experimenting with worksize=212 (and other numbers like 200 or 192) and it seems to be a little faster (1-2 Mhash/s) for some reason..
