7990 quad fire 4k

[steamgamer]

hi forum i have other posts on this topic but if u havent read them what im basically doing is buying 3 dell 4k monitors [24 inch ones] and im struggling choosing gpus. 4x titans are too expensive i can only really afford 2.5 titans 3x 780 ti s would be an option but i dont really like nvidia [any more] 290x only has one disply port and in tri fire or crossfire u have to use the top cards ports for eyefinity so im wondering would i be better to get 2x 7990s for 4k surround as they have 4x 7970 gpus and the top card has 4x minidisplay port connections iv found a place that has 7990s in stock 

 

other specs of rig are [theirs going to be a build log when iv chosen gpus]

-4770k @ 4.8-5ghz [depends what i can get out of it]

-1300 watt antec platinum psu

-120gb intel ssd

-240 gb asus raider express

-2x 4tb segate barricudas 

-900d

-360mm phobya rad in roof

-480mm xspc rad in basement

-240mm xspc rad in basement

-140mm phobya rad on back

all nff12s/nfa14s 

32gb crucial ballistix tactical tracer

asus maxims 6 extreme

av media capture card

xnoar phoebus 

EK plexi gold cpu block

Xspc full coverage 7990 block [ATM]

EK bay res

EK m6e block

EK blood red coolant

 

if anything is worong with this parts list please feel free to correct keeping in mid that total budget is 13k with 4.5k out of that for the dell screens thanks all responses appreciated

Get the nVidia,AMD cards are more expensive than what they should be because of Cryptocurrency.

You could always do it, but 3X 780ti will give you far better performance, better thermals, better stability as SLI is far superior to Crossfire and a better sound level (this also applies if you water-cool them as the 780tis will require less cooling and therefore less rads and therefore less fans to annoy you

 

I would though personally save up a bit more and get 3 Titans as you will be very VRAM limited otherwise...

Says the fangirl. 

 

The price and performance of those cards are still competitive with Nvidia

[Andrew0472]

3 780tis but im just not sure about the vram, should be okay. However you have some really overkill parts like the soundcard and pci ssd which could be replaced to fund the extras for the titans which would be much better

Good luck with that on a haswell chip, they hate being OC you might get 4.4Ghz on a good one with out get thorrotling problem cause of heat, and also the voltage needed will be stupid amounts.

price and performance,but not Power consumption.

+1

 

you have to push 24million pixels. Almost every card would be bottlenecked by the vram amount. The titan is the only card able to push that, i guess.

considering the nvidia slandering you did earlier today about gsync i wouldnt say you are free of being a fangirl either

The AMD Eyfinity solution is still so much better compared to NVidia surround. Why not get 3x 290X, from what I know you can get a splitter for the display ports, but I might be wrong. Why not even get 4x 290X and an i7 4930K?

[Jamdude]

You'll be CPU limited getting cards that powerful and you won't have enough VRAM for 3 4k monitors.

[jscho]

I'd recommend the Titans. Simply because of the 6GB of VRAM. Three 4K monitors will probably be heavily bottlenecked by anything less.

True, was kind of just trolling. 

 

Still, even with more draw the costs in energy are pretty negligible. But it seems these prices need to settle a bit. Guess those miners must be purchasing like crazy, even with the cost increase

[brownninja97]

3x 780 ti better, amd cards have problems when you have more then one of them.

[binman13]

Oh for god's sake, really? Fanboy wars already?

The guy wants AMD, specifically doesnt want nVidia, and is asking for recommendations about a specific card.

Fuck off nVidia fanboys, fuck off AMD fanboys too.

Now, to the actual ****ing question...

Ok...my recommendation would be 4 7970s, purely due to heat and the 7990s reduced clocks, but if you like the 7990s, then ensure that you have proper ventilation and airflow supplying air to both cards. The 7990s seem to be riding through the bitcoin price peak, so thats a point in their favour. 

Now of course the issue is that you have low memory amounts, a problem that WOULD NOT be fixed by a 6 GB Titan...even 6 GB isnt enough to drive 3x 4k displays...

I honestly cant recommend any current-gen cards for 3x 4k atm, they dont have the memory capacity nor bandwidth to pull it off.

If I were you, I'd wait for Pirate Islands later this year, but if you have to settle on cards RIGHT NOW, the 7990s should be just fine...

just putting this out there, 3-4way xfire/SLI scales like crap.

I live within 30 miles of a coal plant any side power isn't a issue

[steamgamer]

but it affectivly has 406mm or rad space just to it as in total rad space for rig is 1220 divide by 3 to get 406mm of rad each

[jezza39]

Due to GPU scaling and power, are you sure you couldn't go with 3x 1440P monitors? You could get away with 2 titans or 780Tis or R9 290s, still get lots of pixels but not break the bank on overpriced 4K monitors, you won't have a great gaming experience if there are lots and lots of pixels, but they're being driven at 20 FPS because you cheaped out on the GPU's

i was orriginally going to get 4x 290s but i found out that disply port can only carry 1x 4k connection at 60hz if i split it to 3 it would be like 25hz each.

but 7990 gets 60fps at 4k so 2x 7990s at 4k would get 120fps divid by 3 and id be getting 30fps at high settings in bf3/ac3 plus i prefer to play games such as jc2 and jc2 multiplayer with isnt massivly demanding

what about at 4k?/effective 12k

Just pointing it out, thats not how the  "#number#k" resolution numbering system works

the cards will be watercooled if i get 7990s. iv already ordered the dell monitors so i need rig now im hopeing to upgrade to  maxwell when t comes out becasue aparantly theres going to be a 12gb card

We can already barely push 4k. Triple 4k is just not feasible without something ridiculous like an Nvidia GRID.
