I only had a chance to test 2 of my systems but I would be interested to see what results you guys are getting. I would also be interested in knowing what psu units you guys have tried with 3x 5970's

Both systems have quad core with only 1 core running at 100%

1300watt rosewell lightning, gold certified
2x 5970's
880 core clock
1555 hash
vddc 1.112 = 795-800 watts
vddc 1.125 = 810 watts
both volt settings seem to work well on this pc
------------
1500watt silverstone, silver certified
3x 5970's
860 core clock
vddc 1.112 = 1170 watts
2250 hash

------
I have not tested recently but I'm pretty sure my other pc had these specs.
1500watt silverstone, certified silver
1x 6990
2x 6970's
core volt +7%
950 core clock
1620 hash
950 watts, its also water cooled with 6x radiator fans.
