Hey guys, so I've decided to go with 2 x 5970s per rig after all. It turns out that I can build a minimal box for less than $200 per card that way (i.e., less than $400 total allows me to run 2 cards).
How much PSU do I need for 2 x 5970s and minimal other hardware? (Sempron 140 CPU, 1 GB DDR3 RAM, etc...)
Edit: How about something like this? http://www.amazon.com/Corsair-Enthusiast-Certified-compatible-platforms/dp/B004MYFODS
It's got 70A on a single 12V rail.

I use that exact PSU in two 2x5970 rigs (CPU is also Sempron 140). Total power drain is around 650W without OC and slightly above 700W with clocks around 850Mhz.
Thanks man! Do you think it would be possible to use the 750W version then?
In any case, I'll have some new miners up and running soon!
