Hi guys, I've been looking for graphics cards, and I've narrowed down the best to these ones: The Evga GTX 580 hydrocopper 2 in quad-sli, dual nvidia quadro plex 7000 (non-sli, just connected), AMD HD6970 in quad-crossfire (if it can support quad-crossfire), AMD HD6990 in dual-crossfire, AMD HD5970 in dual crossfire, AMD HD5870 in highest crossfire mode, Asus Ares 4GD5, Asus 6970 in highest crossfire mode, Asus 6870 in highest crossfire mode, and Asus 6990 in highest crossfire mode. Sorry, I know it's a lot to compare, but that's what I found. I also have a few questions: what is the highest overclock that the EVGA GTX 580 HV2 can get? (not just the regular speed) Note: I care most about speed and how good the card looks (not physically, but as in graphics perfomance) Here's some of the specs for the cards:

Welcome to the forums :)

I'd rule out the Quadro cards straight away: they are designed for CAD etc. rather than gaming performance. I'd also narrow things down by looking only at the latest ranges: so only AMD/ATi 6xxx series cards and nVidia 5xx series cards.

Personally, if money was no object, I'd be getting a pair of AMD 6990s, but you'll need a really good PSU to deal with them in crossfire (they can draw up to 450W PER CARD). Think 1200 W+ ...

rule out the ares to, i doubt you will be able to track one down ( correct me if im wrong ) with the amount your looking to spend i would look at a dual 6990 setup, with a breeze block sized psu.

So you guys think AMD beats EVGA? (Sigh) I never thought I'd see the day...
But another factor is that the AMD 6990 supports dual crossfire, whereas the 6970 can apparently support quad crossfire. If using a single GPU, the 6990 is better, but if you had 4 6970s... I don't know how it would turn out. Also, do you think the number of GPU cores is more important than video memory? Is 6 GB of Video memory enough to run intense gaming applications? I'm asking this because the quadro has the most memory by far, with two plex 7000s you can get 24Gb of GDDR5, but it doesn;t have as many cores as the EVGA... I don't really know lol.

You have some learning to do...

1. AMD is a brand of cards while EVGA, MSI, are a makers of that AMD card. Like Ford is a brand and Escort, Fiesta, Taurus are a make of Ford.
2. 6990 is a dual GPU card so essentially it is quadfire runnign 2.
3. Memory doesnt work that like that. If a card has 2GB, even in Crossfire, each card has 2GB. it doesnt 'add up'.
3a. 1GB is plenty to run most games.

Please answer how many monitors and/or the resolution these will be pushing.

I'll probably be using 3 monitors maximum. I'm confused, though, because the nvidia site says that with a dual card setup (specifically the quadro plex 7000) the memory of GDDR5 has doubled. I guess they just stretched the truth.... a lot. Also, the resolution will be 2560 x 1600.

With 3 monitors, 2 580's or a single 590 or 2 6970's or a single 6990 will do. Resolution will be 7680x1600 in landscape mode.

As far as the memory goes, those are quadro cards and b/c of what they do that is why there is more memory on the cards and they are VERY expensive (along with enterprise level driver support). If you buy 2 cards like I mentioned above, each card still can only use its alloted memory, you do not add them up. So they didnt stretch the truth, at all.

i would also like to point out, to SLI quadro cards is difficult, because they dont just hand out drivers to every John Smith and his cat, they want quadro SLI set ups to be in quality machines so nvidia usually certify the machine first, not really worth the trouble to be honest.

You never know. And with the knowledge this person has shown so far, its a valid statement.

We need to know how the OP is using his PC.

I'll be using the card mostly for gaming, but if a quadro somehow manages to exceed a gaming card's performance, I'd go for that, regardless of what it's main purpose is. Also, the quadro plex 7000 can't do sli, you just connect them physically together. If you read the overview at http://www.nvidia.com/object/product-quadroplex-7000-us.html , though, it does say that with two 7000 cards (equivalent to four quadro 6000s) the memory is doubled from 12GB to 24GB... Still not so sure about this. Another part of my confusion is that the manufacturers don't always put the maximum overclock of the card on the site, just its default speed, so I can't know what its maximum performance is. I have another question, though, lol. Do all graphics cards have cuda cores? I'm just making sure because I think it's exclusive to nvidia. The best quadros have 64 less cores than the best geforce nvidia or evga card. Yet the quadros have way more memory... Which do you think is more important-- video memory or cuda cores?(the quadro 6000 has 6GB, evga gtx 580 has 1536MB (1.5GB), but the evga once again, has 64 more cores per GPU. One more clarification: the number of cores doubles when you connect two GPUs, right?

FORGET the Quadro based cards please and dont worry about its amount of memory as its irrelevent to your now known needs (gaming).

As far as maximum overclocks, no MFG knows as every single card overclocks to a different speed. So no MFG AFAIK posts its 'maximum overclock'.

With that in mind, saying you are ready to purchase this second I would do this in this order.

1. 2 580's in SLI.
2. 2 6970's in SLI.
3. 1 6990.

thanks for the info (and your opinions) earthdog, but I'm not in a rush to buy it... just asking a lot of questions. :) I can also assume by the consant "get rid of the quadro" that that isn't the best for gaming, even with more memory, just because it has less cores, I guess :)

For example, read some of this:

http://www.guru3d.com/article/radeon-hd-6990-review/

and this:

http://www.guru3d.com/article/asus-gtx580-directcu-ii-sli-review/

and you can flip to the pages with the overclocking results as well. Many of their graphs and benchmarks contain many cards, and if you peruse their site and look up other SLI reviews (unfortunately they have no 6990 SLI review up yet) you can get an idea what the cards do, and overclocked as well :)

Edit: The single 6990 is a bit shy of SLI 580s :)

(Sli is a Nvidia tech., CrossFire (and CrossFireX) is an AMD tech.)

If you're still stuck on memory, then you probably don't know what GPU memory is for. GPU memory is utilized differently per game, and having less isn't always a huge deal as modern game engines can simply store information in normal RAM if needed. Game engines use GPU memory mostly to store uncompressed 3D models, shaders, textures, and other information used to render each scene. As of 2011, most games at sane resolutions use FAR less than even 1GB; 3 monitors in a Eyefinity setup (3x1 as you said) would probably benefit from 2GB, hence the Eyefinity edition cards with more connectors and memory.

I think you're under the impression that a 3x1 monitor setup requires intense amounts of GPU power that only insane setups can handle. This is not entirely true, in fact with Eyefinity coming out AMD GPU's in the high-end segment are more than enough for a 3x1 setup. Of course if you want max frame rates and detail, then maybe a multi-GPU setup is worth it.

Keep in mind I am only talking about gaming, I'll get to other things in a minute. Don't even worry about comparing numbers vs. numbers with GPUs unless you really know what you're talking about, just look at as many benchmarks you can with a grain of salt. GPUs like the Quadro and FirePro are made for workstations for HD audio/video editing, photo editing, CAD work, etc. Programs of this nature require tons of memory in contrast to a game. So unless you are doing something like that, don't worry about it too much. (I'd also like to nitpick and note that the Quadro Plex 7000 is not a card, but a deskside GPU and likely requires a rack mount and thousands of dollars to use).

The cards people have recommended so far should suit you well. Personally, I'd go with a 6990 as CrossFire/Sli can be a pain with some games to setup.

Also, what system is this going in? You need a high-end system for a high-end card, along with high-end cooling and power.

Alright, thank you guys! I have one more question, though. Because you're all pleading that the gtx 580 dual SLI beats a single 6990 card, would it still remain the same with a quad SLI (brands other than nvidia can do quad SLI) gtx 580 and a dual crossfire 6990? I'm hearing that SLI is better than crossfire, but I'm also hearing that with the more cards you have, the less difference it makes.(I'm a hardcore nvidia guy, so I have a hard time believing amd is better lol) So you think a quad SLI gtx 580 beats a dual crossfire 6990? And does nvidia have a similar technology to eyefinity (multi-monitor setup?) Alright, thanks again! Feel free to post if you have a different opinion! I'm always open to suggestions! :)

Well 4 cards is really unnecessary IMHO... What motherboard, cpu, ram, power supply do you have? If you really really will not budge on 4x 580's then you better have one helluva system to feed them. When talking raw gaming performance, it's really hard to tell with such ridiculous setups since none of us have them to test and I don't know of too many review sites with 4x 580's and 2x 6990's. Do you have a budget or anything? There's always a best setup for someone, we just need more criteria before we can recommend something.

Quad sli 580 gtx is overkill.. The only people running such setups are benchers. I don't think there is a game out there that would make 4 580 gtx's work hard. Nevermind the power usage also LOL! That being said its your money ultimately :)
