Picking The Right Motherboard

The GeForce GTX 480 Update: 3-Way SLI, 3D Vision, And Noise
By

Generally speaking, it should be “enough” to buy an SLI-capable motherboard and expect your dual-card array to work. That’s technically true, but when it comes to the GeForce GTX 480, there’s a right way to go about picking a platform.

You want a board equipped with two second-gen PCI Express x16 slots that are electrically wired to run at x16, and not x8. Moreover, you want them to be at least three slots apart, leaving at least one space between the top and bottom cards. Anything less and you’ll sacrifice frame rate and/or acoustic performance.

Fortunately, there are quite a few boards with ample spacing. Some of these include:

Motherboards With Ample Spacing For SLI

X58 Express
P55 Express
AsusP6T Deluxe
Maximus III Extreme

P6T Deluxe V2
Maximus III Formula

P6T Deluxe w/ OC Palm
P7P55 WS SuperComputer

P6T WS Professional
P7P55D Deluxe

P6T6 WS Revolution
P7P55D EVO

P6T7 WS SuperComputer
P7P55D Premium

P6TD Deluxe
P7P55D Pro


P7P55D-E Deluxe


P7P55D-E EVO


P7P55D-E Premium


P7P55D-E Pro


SABERTOOTH 55i
EVGA
X58 Classified 4-Way SLI
P55 Classified 200

X58 SLI Classified
P55 FTW 200

X58 SLI

Gigabyte

P55A-UD4P


P55A-UD6


P55A-UD7


P55-UD4P


P55-UD5


P55-UD6
MSI
Eclipse Plus
Big Bang Trinergy

X58 Platinum
P55-GD80

Eclipse SLI
P55-GD65

X58 Platinum SLI
P55-GD85


Now, obviously the P55-based boards are going to give up some performance, as integrated PCI Express connectivity on LGA 1156-based CPUs gets divided into a pair of x8 links. But if you're going with an X58 board (and if you're spending more than a grand on graphics, I'm willing to bet you're also running an LGA 1366-based processor), double-check your platform of choice, ensuring the properly-spaced slots are both of the 16-lane sort.

Again, we’re using MSI’s Eclipse Plus, which comes armed with an NF200 bridge chip, capable of multiplexing the chipset’s connectivity into a trio of x16 slots for our three GTX 480s. Special thanks to MSI for also supplying that third card.

    Did I miss something, but there is NO mention of the power consumption of the 3 x 480's??

    lashtonand why not check it against the 5890, the 480GTX is nvidia fastest card, put it against ATI Fastest Card


    A pair of 5870s is actually going to be faster. Should I swing a second 5970, though, I do think a pair of 5970s vs. the three GTX 480s would be a good comparison!

    Why don't you overclock that cpu higher? Only 3.3 Ghz? The 3rd GTX 480 looks like it's being bottlenecked. You can see the scaling is excellent at high resolutions with AA (from 1 to 2 to 3 cards), but at lower resolutions without AA there's no gain.

    There's a good chance that more CPU would def. help at the lower resolutions--one of the reasons I chose 2560 for the comparisons at the end ;-) For one reason or another, wasn't having much luck getting the retail i7-930/Eclipse Plus combo to overclock very well.

    I have no clue where you people are getting this "5890" Statement from... They have the 5870, and then the next step up is the 5970... Is that what you're trying to say?

    Quad fire with 5850 would have been nice (thinking back to a builder marathon with quad fire) to see if ati's quad cards made any improovement over last years ones. Also i agree with lunyone, I for one would have been interested to see the numbers on load for the 3 nvidia cards with the 800W gold power supply (and maybe a comment from you cris about what power supply u think is best for the job. Either go lower wattage but a high efficiency psu or higher wattage but lower efficiency)

    Anyways, it was a informative article, looking forward to a full 512 sp card from nvidia and the second revision to the fermi core.

    The only place where the "5890" exists is in ATI's folder under 'What to do if Fermi is good".

    And yes where is the tri-sli power consumption numbers, there's no mention of it's omittance in the analysis.

    Actually, addressed in a couple of different places ;-) As mentioned in the test setup section, the 3-way SLI numbers crested 900W under load. But because this was above the Enermax unit's max. continuous power rating, this almost certainly isn't a very efficient measurement. Not that it matters--the noise of three cards was so loud that it's simply not a realistic combination using the Eclipse Plus board.

    Who wants to pay $10 for 1 fps?

    I'm going to stick with my old 9600 SLI config that I spent $100 dollars on a few years back.

    dummy...the 5970 is a dual gpu card, that's why it was not compared. as far as since gpu cards go nvidia is the fastest one out ther.

    He wasn't able to upload the results before the power outage caused by the setup.

    What couldn't get your hands on a 3rd HD5870? Also ATI makes Crossfire bridges long enough. I got 2 with my MSI K9A2 Platinum, and another one with my MSI HD5870.

    I do wonder about how the results are presented. Its obviously given in a method that favors nVidia. The only results chosen to be highlighted are the only results that show AMD in a poor position. I think to present these findings to consumers is rather misleading and more information should be furnished so consumers can make a proper decision on a product.

    Right now the most common resolution is 1680x1050. 1920x1200 is becoming more popular as well. At these resolutions even considering a single GTX480 as having a performance advantage is questionable compared to an HD5870. The HD5870 also scales better in those scenario. Yet the basis of your conclusion of consistent SLI scaling comes from the least favorable scenario for the HD5870 on resolutions that are uncommon. I don't think its a mystery why a lower memory card would perform worse doing a post processing effect at a large resolution. However, there is more to a graphics card then memory and its evident the difference in architecture choices at common resolutions.

    always great articles from u chris, hoping u might take on the 5970 and 2x5970 soon.

    So, I'm wondering how much of overclocking potential these GTX 480 cards have. Yep, they are running hot as it is. But, what if you throw liquid cooling on that 2X SLI setup to keep the temps at 35C highest. How far would they go then?

    For those who are brave enough to peak at the power consumption of 3 480s running at the same time:...
