Lucky buggers..

Not very impressive... tons of bugs and issues with the setup and 32xAA is just plain useless. Heck its performance isn't what you would expect aswell... 4 cards sometimes barely beat 2...

Nvidia should just drop this BS and continue to work harder one making a killer G80.

What will the 7950 have over a 7900? :D

Looks like some bugs.. and sometimes slower! But overall its a bit faster at 1600x1200 in most games at 4x/16x, but most of the time much faster at 2560x1600/1920x1200

It destroys the x1900xtx's in oblivion at 1920x1200

It dam well better at the cost to achieve that performance, I would still rather buy two X1900XTXs then four 7900GTXs...

I think that nV maybe should work with developers working on specific settings that would take better advantage of quad SLI.. like maybe higher poly models, or whatever.

Higher AA settings are nice and dandy, but for any games that use FP HDR you won't be able to use any AA at all!! So what are we left with to take advantage on Quad SLI?

I didn't read the whole preview, did they mention what PSU they used ????

Enermax 660w...

Hmmm.. that seems a little low for cards that draw 150w each. But, it was built by a system integrator, so they know whats best.

One of these cards will be perfect as my motherboard doesnt support sli. I have been seriously considering the Asus 7800gt dual card but it is just too expensive.

I'm curious to see how this performs on a dual 8x board rather than 16x...

And Lee, that FSP drops the +12v by an incredible amount when under load with XFire... I would steer clear of that one for Quad SLI. I'm willing to bet it will hit close to 11.80v with Quad SLI.

The clocks on each card are slower, that could explain the "bugs".

Still, 10-20 FPS gain at higher resolutions isn't worth it for me. And I simply don't need 8x AA at 1920 or 2560...

Well, I think the lower performance is due more to the overhead caused by balancing the loads.

Like jAkUp said GX2s where handicapped with that 660W PSU and there I doubt that these are true QuadSLI performance numbers. Not that I am saying Xbit labs jumped the gun to test the QuadSLI with inappropriate drivers/config/mobo bios. :rolleyes:

Anyone else thinks that XBit labs will come crawling back like their "dressed to kill" ,"love at second sight" drama.

Looks like Quad SLI still needs time to mature ... there are still some good results here & there though.

They test it with a 1 Kw PSU too.

4 cards cards is pure over kill:thumbdwn: waste of money if you ask me.

As you can see, Quad SLI is extremely valuable for owners of the Dell 3007. So therefore, it is not a waste of money to them. The results at 2560x1600 are pretty impressive for the most part.

Of course, at anything below 1600x1200, the results are not quite as impressive, but come on, nobody expected it to be right? Thats a massive CPU limitation at those resolutions, it only gets impressive at AA levels above 4x.

Nice trollish 1st post BTW.

I like QuadSLI. :) Gaming at that res with Dell 3007 must be truely next gen and an insane experience. :drooling: I do think that the G80 QuadSLI would be more valueable and futureproof but then again, people who are able to spend that much money on super-high-end computer hardware, won´t have a problem to buy G80 QuadSLI once it becomes available and give the old computer to their wives. lol

QFT. It would be a bit less obvious if the poster had produced more of an argument then just a..er waste of time. I bet with a more powerful CPU like say conroes, lower resolution benches might be different to overcome CPU limitation to a certain extent.

Definetely. It is quite obvious that he is being CPU limited at 2.6GHz, I would imagine that with a slight OC, you will see huge performance gains.

Shamino or one of the extreme overclockers should get of the GX2 cards on their 4 GHz FX or 5 GHz Penitum4s. That would be interesting.

Not really an option until the clock speeds of 500 core and 1200 memory are raised. I hear that the 7950 is the mobile 7900gtx go chips. So, I do not think we will see the increased clock speeds that are holding this setup back at the moment.

Four GPUs and slow memory. hummm

As we all can see, when we overclock the memory on the 7900gt or 7900gtx that is where the performace gain is.

Wish they would put the 1.1ns memory that the 7800 gtx 512mb cards had on the Quad SLI cards. Might change the tune quite a bit.

Who knows, maybe a voltage mode or massive overclocking would make these come to life. I fear that cooling will be difficult due to the layout of the cards.

Thank,
Monnie
