6990 or 7990

[Bajantechnician]

 should i get a 6990 or 7990? i need it for 5 monitors in eyefinity. im not sure if the 7990 is worth it. and i also have a budget for about $2500 US dollars. www.youtube.com/watch?v=0GHiNaEZt-k

Neither. GTX 780 SLI or GTX Titan Black SLI.

For FIVE monitors? If you're gaming, you'll run out of VRAM very quickly...

I run out on three with a 780...

http://www.newegg.com/Product/Product.aspx?Item=N82E16814202094 , you could almost get 2.

But for the price go for a Titan black or something

[Jvagle875]

7990 for 5 eyefinity monitors? Doubt it... 780/780ti sli perhaps

[flibberdipper]

Get two Titan Blacks for the love of GPU's...

[Ryan Leech]

The 6990 can barely handle 1080p... You are going to need 3 Titan Blacks

But the video...

That was March of 2011 when 1600p used 512MB vRAM

[acidydragon]

But the video...

I'm just letting you know, my 780 has issues with THREE monitors. As games get more intense, so does hardware.

[ForsakenLive]

But the video...

Those were old games my friend, also mid settings.

2x 780tis or Titan blacks will drive that resolution

Can you please elaborate significantly with what your desire is? You need 5 monitors? For what? Please describe what setup, programs, and games you'll be using on it.

 

Yes, the 6990 could do 5x eyefinity in 2011 when it came out, but games are significantly more demanding now.

 

The HD 7990 could definitely do 5x Eyefinity, but you may still see frame drops below 60FPS (or even 30FPS in some games).

 

If you have a $2500 budget, then getting 3x GTX-780 Ti would be your best bet, and that would run you $2400 + taxes. You could also go with 2x GTX-Titan Black Edition, but that would be the same price, and 3x 780 Ti's would be better than 2x Titan Black Editions.

 

Also what CPU, ram, etc, are you pairing with the setup? What motherboard? What PSU?

You seem to really want the AMD cards eh? The HD 7990 actually should be fine, as long as you're ok with occasional frame drops. This is from Computex 2013:

I would go with either the HD 7990 or 2x (or 3) GTX 780 Ti.

i like mantle, but does amd cards have 3d?

Get two Titan Blacks. You will need to VRAM and they will run cooler and perform better than a 7990

[GamerDude]

Why the HD7990? For surround gaming, AMD is easier to setup AFAIK, so going AMD make sense. The HD7990 has 6GB or VRAM, but each GPU has access to only 3GB effectively making it 3GB/GPU. Your best bet is to go 2x/3x GTX Titan or 2x/3x R9 290/290X. Although the 290/290X has 4GB of VRAM, it should be sufficient to drive up to 5 monitors (in portrait mode I suppose) as long as you don't get too aggressive with the AA setting. I have 2x R9 290X driving 3x 1200P monitors, and they are fine although I do max out ingame setting whenever I can.

 

For 5 monitors, perhaps tone down AA a little. I've read somewhat that for more than dual card systems (that is, 3 cards or four), AMD cards tend to scale better. For dual card setups, CFX and SLi scale about the same with negligible differences between them.....except for games that favor one over the other that is.

 

BTW, before going two way R9 290X, I had a 3 way HD7970 CFX setup, I saw less issues with micro-stuttering that many with daul card setups complain of. I managed to play a good variety of games at max or near max setting @ 5760x1200.

[Bluuz]

Should probably re-evaluate your priorities and do some research before dropping $2k. What's your current configuration? 

[Gunjob]

For that kind of money you could buy 3 aftermarket cooled R9 290x's here in the UK.

[DIV1D3]

2x Titan Blacks, you'll need it for 10,368,000 pixels!

[maazster]

Just wait and see if there will be a R9 290X X2 card, its not all about vram but rops as well in this case.

Sapphire has there own r9 290x with 8gb of Vram, probably wouldnt get to use it will with the 512 bit bus but if you had to itd work?
