fascinating thread
currently running a 5770 with a 20" Apple Studio Monitor (which, after 10 years, still looks FAR better than my Samsung monitor). I'll be looking to upgrade to a high res monitor if/when Apple comes out with one (or they get a bit cheaper), so I'm watching this thread with great interest. Looks like the Titan is the winner thus far, but 30 Hz would still be painful to use.

Quadro 5800 = GTX285 + 3GB more VRAM - slower clocks
I had a theory that perhaps more VRAM would help, as each frame of video is now 4x as much info as an HD 1080P screen .
So I was trying to think of how to test an existing card, but add 4x the RAM.
Answer, the Quadro 5800.
I finished work on these some time ago, but need to fix one last thing. But you never know when fixing one thing will break another.
Anyhow, a Quadro 5800 is, for all intents and purposes, a GTX285 with 4GB of RAM instead of 1 GB.
But it turns out the the lowered clocks had more impact then the quadrupled RAM.
Scores went down from GTX285. Ah, but just 1 FPS you say...but when you only have 7 fps to begin with , that is a significant drop.
So quadrupled RAM (and the Unicorn Hair imbued silicon
) didn't help this down clocked GTX285.
Note the Cinebench score, perhaps they have made it relevant again.
The DP port gave nice boot screen, then crashed before desktop.
Only way to see clear screen was the magical DVI to MDP adapter from Atloona.

Hair of the Unicorn that bit you - the K5000 and Tesla C2070 (Fermi 6GB) take a shot
Here we have some very pricey Workstation cards.
The C2070/6000 was king of the Fermi hill, it's CUDA-Z spy score is similar to a GTX470. In 4K on Valley, it doesn't do especially well. On CInebench, it is able to best the Quadro K5000 as well as the Quadro 5800 (4GB).
The Valley scores come out differently. The K5000 with it's horsepower more firmly in newer OpenGl stepped up, and the Q5800 moved to back of the pack.
It can only be assumed that CInbebench is measuring memory bandwidth or some subset of older OpenGl where a 5800 can trump a K5000.

Have no problems. Remember I'm driving 3x 27" monitors so it's just a tad over a 4k display in pixels. 4k = 8,847,360(4096x2160) I'm pushing 11,059,200 (4320x2560) and possibly soon 18,432,000 (7200x2560) but only if I get another titan lol
I'm only currently limited to 60hz because of my displayport > duallink dvi adapter. The panels clock to 120hz just fine. Only downside are the bezels because of the mulitple screens instead of a single smaller panel with much higher pixel density. I'd love a single 120hz 4k display though
Not awful, just awful considering the untold thousands of dollars users will pay for a pair of them when a pair of Titans (likely for less $$ than dual D700) would mop the floor with them.
I wonder what the 780Ti will look like, or the R9 290X. The nMP is getting clobbered before it even comes out.
Hopefully that [interesting person] talking about $2 nMP --> standard PCIe adapter was right about potential upgrades to standard cards, though I'd hate to see the end result.
Are those images scaled correctly? That would make the new Mac Pro the size of a soda can lol.
Flashing Q5800 for Mac use
No kidding.
Question for MacVidCards:
I have a good Quadro 5800 with SDI option board, it's a pull from a PC we just installed a QK6000 on. I'd like to use the 5800 in a MacPro 4,1 or 5,1. How would I go about getting it flashed for Mac EFI, and what drivers should I use? Can do without SDI part since that's covered by Kona and there's no slot room for it anyway.
Main apps on workstation are FCP7, AfterEffectsCC, PremiereCC, and AvidMC6.5, running with AJA Kona3. Current graphics board is a stock nV GT120 or a ATI Radeon HD5770.
Not afraid to upgrade the OS10.7.5 if there's an advantage to doing so.

Quick 4K update
So, mixed bag.
4K @ 60 Hz is still a "Bag of Hurt" in OSX.
I finally realized that even vaunted GTX570 can only do 30 Hz in Windows.
I have tried running both DVIs using the Dual HDMI input, it crashes every time. Same with GTX580 using Dual HDMI. Move a 680 or later in, BINGO, it works.
And here is where it gets embarrassing. A single slot GT640 can do 60HZ in Windows using Dual HDMI trick.
But don't get the impression that this is easy or pain free in Windows. When in 60Hz mode, you lose some Windows boot screens, or they only show up on one half of screen. It takes the main drivers to pull off the 60 Hz thing and these aren't there during boot up. So it is well documented issue in Win with these displays.
Gets easier when same GPU always connected. But when you try to test a variety of GPUs, the drivers don't load right away and you get lots of black screens and thinking that machine crashed. Switching from 30 Hz to 60 Hz mode requires lots of tedious button pushing. Torturous.

Do you think the attempt to implement 4K functionality has anything to do with the depreciation of Cuda in some of the older cards or do you think it's strictly a coincidence?
I am still hopeful that the GTX285 losing CUDA in 10.9 is an oversight and will be fixed.
Aside from which, ability to run 4K is directly a function of pixel clock while CUDA level is determined by architecture of core, very different things.
thank you for enduring the tortures and keeping us up to date with the latest developments.
i have really bad eyesight and am sooo looking forward to 1920x1080 @ 2x on a 32" 3840x2160 panel. at the moment i'm using a 40" samsung display with 1920x1080, those are big pixels...

Isnt half the torture in windows due to the half baked way these displays are - a 2 panel bodge instead of a complete native 4k panel?
Have you tried the 10.9.1 beta? Maybe it has some new mac pro drivers that would support the 4K output at 60Hz
Bump.
Hey MacVidCards have you (or anyone else) tried the 4k display with any of the Nvidia cards with Displayport 1.2 support, i.e. the 760, 770, 780, or titan? Would love to hear how that worked out.
Also, a slightly related question, how usable is a monitor with that high of resolution without scaling it down? Text still big enough to read and all that?
Thanks,

Politics? You mean people who don't want to hear again and again how video card replacement is the be-all-end-all of computing, and therefore the nMP is the worst computer of all time?
What are you talking about? I'll certainly miss all his "unbiased", "disinterested" opinions which have "nothing to do" with his "business".
I'm almost sure he will be back on this forum as soon as he need to sell some more flashed GPUs.

A big loss indeed. Sometimes vitriol from ignoramuses is held in higher esteem around here than bitter criticism from experts. Shame we can't take a little grouchiness from MVC without chasing him off.
Does anyone here have an idea whether certain after-market AMD cards are likely to benefit from video card developments in the new Mac Pro? Still trying to decide what to switch my 5770 to...
