2x GTX 570 SLI + Antec 650 PSU - testing
 
On a whim I'm trying the 570's in SLI. To be safer I de-overclocked everything... I've done a bit of gaming/benchmark testing and thus far everything is holding up fine. I guess I gotta give props to this Antec Earthwatts 650 PSU. The only weak point of this system is the big vdroop on this Asus motherboard...

idle GPU temps are **EDIT** 42... 4-5 degrees higher than with one card.

So how long before I blow a cap? :D

Don't you have a Kill o watt(sp?)?

I can't give you a direct comparison, but my 480 based rig reads (pc only, no peripherals) 452w while running furmark at stock speeds....yeah, I'd love to see how close you're cutting it.

also i'd be interested to hear, rage, what your impressions are about 580 v. 570 in games. i saw you review and read the benchmarks, but i'm curious if you have any subjective impressions about the difference between the two cards.
