ASUS GTX580 SLI Exclusive Review
Test Setup and Overclocking

Test Setup
Not only are we testing in SLI today, but we're also going to run the single card too, just to see what the ASUS version has to offer with the Voltage Tweak. We'll compare against the stock GTX480 again, and also two GTX480s in SLI at stock speeds.

Intel i7 950 @ 4GHz
6GB Mushkin Redline RAM

Windows 7 Ultimate 64-bit
Overclocking and Temperatures
Being an ASUS card we have two methods of overclocking available to us. The primary way is the same as always, ramp up the speeds until it cries enough. Using this we were able to increase the GPU Core speed from 775MHz to 882MHz.
The second way is to use the ASUS Voltage Tweak to help stabilise the card and hopefully eke even more speed out of it. Using this we hit a whopping 950MHz on the core. A massive increase.
If you were running the cards in a water-cooled setup, or perhaps you're deaf, then you could certainly get even more performance out of the cards with the Voltage Tweak BIOS.
The ASUS cards performed so much better both in overclocking and thermally than the Zotac we saw yesterday that we're wondering if either the Zotac was an unlucky chip, the ASUS is a lucky one, or some combination of the two.
With auto fans the card barely span up to an audible level and was noticeably quieter than the Zotac.

It is a shame that I bought 2x460 SLI - I should wait and buy 1x580 from Asus.
Did the performance dip down at all when you had it clocked up to 950MHz on the core at all?? If it didn't then the issue of the card throttling before any decent overclocking can be done is blown out the windows.
Does look like you had a poo poo Zotac though.
Oh yeah and the SLI scaling in Metro is pretty decent.
Reason I ask is because in the video for the Zotac it was disabled.
It's all getting rather confusing ay.
I know the card throttles if you use furmark or occt from logic in the card somewhere but I'm not sure what other throttling it'll do. Perhaps the furmark and occt are done on TDP while the rest of the throttling will come in to effect when the card gets too hot.
That would make sense as Nvidia did say that the throttling wouldn't effect gaming in the way it does the torture tests.
I don't bloody know, just theorising.
Anyway, it does show that a nice aftermarket cooler should allow some nice beefy overclocks that definitely have a decent effect on frame rates.
Here it is for the forum go-ers anyways

Physx off. Physx on?

The rolling benchmark looks completely different with Physx enabled mush.
Found another comparisson shot. Off

Doesn't matter really, but man, this game with Physx on is a sight to behold tbh. In the benchmark it's literally smoke and cobwebs. In the game? tiles smash, scenery breaks. Absolutely amazing stuff.
Ed. What I mean by doesn't matter.. In a benchmark as long as it's the same across the different hardware you are generating a comparisson. Those cards will absolutely eat Physx up any way
Edit. Again where are my manners. Thanks for the review chaps. Gives a man a chance to see how the rich and filthy live
Haha it's a good thing for you guys really. You have all the top end expensive stuff which makes me not want it as badly
but yeah nice cards, only if i had the money
though i still love my 460s
you need to get 2
lol
