Anyone with 3x hd5970 or 3x 480gtx eyefinity ?

[venur]

I want to know if anyone run a 3monitor set-up (5760x 1080p) with either 3x crossfire 5970 or 3x sli 480gtx. Reason is that I plan to go for 3x GPU for a resolution of 5760x 1080p and I don't want to upgrade my GPUs till the 9000s and 800s series will be released.

So anyone with that set-up tried BF3 or any other high demanding game in a 3 monitor set-up ? Can it max the game ? Can you go ultra setting with 4aa ?

The GTX 480 does not do Eyefinity that is only for the AMD cards and the GTX 480 will do Nvidia's three monitor surround setup.

With three GTX 480's in three way SLI you will be able to play BF3 at ultra settings.

3x 480's will be great, but do remember the heat they output.
Your sig mentions 2-way 680 SLi.... i am now confused.com

I'll go 2way cf or sli for now and I'll buy the third one when the next generation GPU will be released (price will have decrease and I doubt that I would realy need over 2 card for anything untill then).

As for the heat I got a corsair 800d that I'll watercool putting the rads outside of the case.

And well as of now I.ll maybe end going for the 7970 instead of the 680gtx. Depend if I want more then 2g of Vram or not.

Since the v-ram is solely for the video card to use for the display 2gb is good enough for even a 30" at 2560x1600 and with Nvidia saying that the 680 will do three monitors with one card then that means the 2gb will be enough for the three monitors. I'm sure that three gb will be better but all the benchmarks I've seen show two 680's being better than two 7970's.
I currently have three GTX 580's and my performance is great with either two or three connected. I had to RMA one of the cards so I ran with two for a while and still was getting great performance and that's in games like BF3 and MW3.
Also water cooling does take care of the heat issue and it takes a full blown stress test to get over 40c.

3monitor BF3 ultra with no aa eat 1.8g of ram. As of now yeah 2gb is enough exept for poorly coded metro2033 (seen it over 2g) But well I won't be replacing the GPUs for 2years or so. Crysis 3 will probably beat the 2g of Vram for 5760x 1080p but even if it isn't I wouldn't be surprise to see games using more then 2g of Vram in 3monitor set-up before I want to upgrade my cards.

And well even if 2g of Vram would be enough I'm still not sure wich card I would pick up. 3x 680gtx cost more then 3x 7970 +3free games. If the radeon can run everything at max quality till I upgrade, their is no reason to pay more IMO.

Anyone think that 3x hd7970 would lack power to cap graphix in 5760x 1080p before they release the 9000s and the 800s ? I have lots of money to spend on the PC but I hate to pay for feature that I won't use. Kinda why I went for the i5 on such a high priced build. The i7 might be only 100$+ but I won't use hypertrading so why paying.

It's certianly nice to have lots of cash for spending so you can get what you want but at the same time you do have to be careful and do your reasearch so your not as you say paying for something you can't use. The biggest issue I have found when trying to get the video cards that I want is the Pci-e structure on the motherboards. You have to make sure that you have enough lanes for these cards and not be stuck with putting a video card in a full size slot that only has 4 lanes left available for that slot. I want to see a motherboard setup with 40 lanes of bandwith available for those Pci-e slots so I can do three cards and at a minimum have x8 x8 x8 or x16 x8 x8 , on the board I have now if I just run two cards I can get x16 x16 for the two slots and it's an X58 chipset motherboard.
Your motherboard has this , 4 (x16/x16/0/0 or x16/x8/x8/0 or x8/x8/x8/x8)
so you will have to be careful about putting any other cards in the other slots ( nic cards , sound cards etc) as that will change what the pci-e lane bandwith assignments are.

I already have the mobo: http://www.newegg.ca/Product/Product.aspx?Item=N82E16813131822

4x PCIe 3.0 (only need it for 3monitor set-up as a 2560x1600p do not bottleneck the PCIe2.0) run in 4 (x16/x16/0/0 or x16/x8/x8/0 or x8/x8/x8/x8).

I just can't wait to receive my new CPU to use

So now I must figure wich GPU I want to buy. I just need something that will last me till the 9000s/800s at maxt setting in 5760x1080p.
