Crossfire 5870's recommend 600-650 watt PSU. I'm hoping they don't use much more power than the 5870s because ill have to replace my 750W PC PNC PSU as well if I want to SLI GTX480's...

If its really 280W like the rumor says, you'll probably need an 800W power supply minimum for SLI, maybe even 850.

Cant wait for the Fermi to come out.. Im hopefully going to step up my 2 GTX 260s that Im getting via EVGA RMA since one of my 8800gtx's kicked the bucket (if theyll let me) to GTX480s. Should be sweeet.

Its highly doubtful that my PSU will power both though (PC Power Silencer 750). :/

Evga doesn't let you step up RMAs...

The GTX470 isn't their highend, its their second tier highend. And why can't you believe it? If clocks are but 1 of the 2 reason the 512Sp part isn't available, why is it so hard to believe lower clocked secodn tier part? ATI is doing with the 5850 vs the 5870. The 5830 will have even lower clock than the 5850.

Yes, but you're saying they're going to launch the GTX 470 as the highest end card for a month or more? No way they'll do that... If they're going to only have 448SP cards they'll have a GTX480 with higher clocks, and then replace it with a 485 when 512SP parts become viable.

I would not bet on that.

Yeah, it'll give you an advantage in MP, because you'll have a wider viewing range than most other people.

And Eyefinity's not all that expensive. LCDs are a dime a dozen these days. I got all three of my 23" 1080p screens for less than 520$.

What resolution does that put you at? Most games won't support those resolutions correct?

nvidia has the same option do they not? I seem to remember hear about it... I haven't checked in as thats the one thing that would bother me, was the lines in the monitors. I have a serious issue I get headaches if anything is distracting me. I could watch TV and if the covers on the bed I am laying in are up even a bit, not even really infront of the TV it will distract me, and I cannot watch TV unless they are completely out of my field of vision. I guess I am weird but I get headaches, and bothered by objects in the back ground, and those lines from each monitor would be very bothersome. If I ever decided to try this I'd like them to just make a big monitor to support that type of resolution, that'd be awesome.

Incorrect. Most if not all modern games support Eyefinity.

Incorrect again.

Nvidia cards can do it, but you have to use a third party software called "Matrox to Go." And it costs 300$.

Eyefinity is in-driver and is free.

I believe that Nvidia may try to do something similar with Fermi, but I don't believe that it's a certainty at this point.

When fermi launches, in order to support 3 or 4 monitors, you will need SLi to do it. Also the tech is going to be available for the GTX2xx line aswell. Nvidia will have 2 versions the 3D surround where you wear glasses and use(best option really as 60Hz displays will just hurt the eyes) 120Hz LCDs or you can use the tech in standard 2D mode much in the same way that ATI does it now(albeit from 1 card tho).

Just to point out, it will still work on 1 card, but you are limited to 2 screen as there are only 2 outputs per card. Less that ideal, really.

no, it makes perfect sense. 3d Stereo output requires more horsepower to maintain the same framerates (be it Nvidia's 3d or ANY other 3d) so you would want SLI anyways. Also, you want more horsepower for larger resolutions (I know because I still have a 30" Dell monitor as well as all my other monitors). There are some times when AMD's six monitor output card would do well but those are not gaming situations.



Dunno really,but i'm betting my pair of HD5970's in quad crossfire would likely handle 6 30" displays at their native resolution in most games out there,since ATI follows the late 3Dfx philosophy that any new feature is only worth supporting if there's enough performance in real world gaming terms to justify it in the first place,while other companies have introduced new features in the past simply because it looks cool in their tech demos,and it's something to boast over your direct competitors.



Anyhow,is there still any fresh news regarding Fermi's release,as in when it's going to happen?....We're in the middle of february already,and at least an official date with reviews from the major hardware sites would be nice at this point....It's too quiet basically.

Even though the 5970 is by far the fastest card on the market. I bet it couldn't run 6 30" displays at acceptable rates in 3d ( if and when ATI support it) in there native resolution at acceptable frame rates. At least not with everything on high and lots of AA. 3D really is a performance hog. In saying that though, there is simply no better game immersion around period.

You'd still need 2 HD5970's to run 6 displays,as it can't be done with a single one anyhow(the limit is 3 displays),and some sites have reviewed 3 display setups with a single card,and it's running them very smoothly at high settings.


Put it this way,a single HD4870 card is still a very decent gaming card and able to run pretty much every game out there on a single 24" display at pretty high settings and the overall FPS performance is smooth enough to remain playable in the majority of cases.


In terms of raw hardware resources as far as shaders,texture units and Rops,a pair of HD5970's have the same number of rops,shaders and texture units as 8 HD4870 cards combined....Still think it's going to struggle running 6 30 inch LCD's at their native resolution,on most games at pretty high settings?....I don't think so :D



In short,HD5970's are monsters,and ATI are going to EOL the current HD5800/5900 lineup by the end of march supposedly,as new refresh cards are going to be released by early april it seems.....Right when Fermi is supposed to be released incidently.


Looks like ATI are already preparing a warm welcome for Fermi.

3D cuts your frames in half. So yes I still think it would struggle. :)

Plus 1GB per GPU is simply not enough for gaming at 6x 2560x1600.



Then why did they show demos of games running with 6 panels on a pair of cards?....The only thing we can take for certain is that the 6 mini display port version of the HD 5870 needs 2 GB onboard,and it's been delayed to Q2/2010,given that it's used only for pretty specialised applications anyhow.


Anyhow,the overall situation for Nvidia is pretty crappy given that ATI has basically introduced their entire lineup of DX11 cards,covering from 60$ budget cards,all the way to the highest end ones,before nvidia releases even their first high end DX11 model,so they're lagging behind in a huge way here,not just on the high end,but all price points and models,which the lower end versions are the ones that sell in large volumes and pay the bills.



Anyone care to bet when we'll see a midrange 250$ card based on the fermi architecture from Nvidia?

Running a game and getting the max out of a game are two different things. Demos like that are often a bit tricky because they don't fully reveal all the settings.
I don't know what demo/presentation you're referring to but I have my doubts that I'd be happy with 5970 Crossfire for a display configuration like that. And I'm not talking about driver problems...

It's good that ATI has so many products out right now but their situation is not perfect either. Otherwise I'd be still using a 5970.
Today we have so much GPU power and thanks to the console boom there aren't that many games that can use all that power. So for me the whole package is getting more and more important, not just raw performance.
I don't care how fast those Fermis will be and who's going to have the faster card. As long as Fermi in SLI is fast enough for 1080p 3D gaming, that's all I need for the next few months.
Hopefully some of those new 3D 50"+ LCD TVs will be 3D Vision compatible...


Can't vouch for a triple 30" LCD setup running at native resolution,but i did see with my own eyes at the local shop where i buy my hardware,a triple 24" LCD setup running on a single HD5970 card at their native resolution,with a variety of games and their in game quality settings cranked all the way up,even in the battlefield bad company Beta demo,and the games were running very smoothly all the time,so it is a usable feature in practical terms.


It's just a shame that hardware review sites didn't really review triple display beyond a few minor comments here and there,as it would be informative to actually post benchmark results with that configuration,so that users could see it's actually pretty usable in game,and not just a check box item,or used only in tech demos.

Here's the only site that actually did a review of eyefinity using a few different models of HD5700/5800/5900 cards,and a single HD5970 did a fine job driving those 3 displays in most cases.

That is pretty much what i'm looking at myself. A couple of Fermi's and a 46 to 50" 3D TV for the ultimate immersion. Not interested in 3 screens for gaming at all. I just couldn't get past the 2 bezels. It would ruin it for me. But each to there own, if that makes em happy. :)

It's really a bit of a strech to state it's the supposed release period either,just unconfirmed rumors,even if they're coming from several hardware sites....The definitive answer is with Nvidia,and they've been silent on release dates,performance,power use and prices.


With ATI possibly releasing refreshes of all their cards in that same rumored timeframe that Fermi is supposed to be released,and even if Fermi did have a performance lead with the original HD5800 lineup,will that be the same with the refresh versions?


Has fermi's window of oportunity to shine as the fastest card on the market come and gone,given all the delays it's suffered so far?.....That's the main question.
