gtx 690 sli , 780 ti phantom sli or titan black sli

[siriuslee]

Hello people,
I currently have an Asus Nvidia GTX 690 which i was think about getting another one for sli set up. I will be building my windows 8.1 gaming pc soon and would like to use the fast boot feature of windows 8 which you need a uefi bios motherboard, hard drive, uefi vbios graphics card along with windows 8. My GTX 690 does not support uefi vbios out of the box but there is a flash uefi update tool via the asus website. As i have not built my gaming pc yet i installed the 690 into my sons pc to flash it to the uefi bios but because his motherboard does not support uefi i have to buy a board that does and some other things.
My main question, rather than getting another 690 do you guys think i should go for a 2x Gainward NVIDIA GeForce GTX 780ti Phantom sli (these cards come out of the box with uefi bios) or titan Black sli or just get another 690 and flash both of the cards.

Many thanks in advanced

Personally, I wouldn't pick any of your choices

I'd certainly go for 780ti's but not the Phantoms - they great performers but they dump a ton of heat in to your case. Two of them would just cause you grief.

What are they for? gaming only? 1080? triples? 1440? 4k? 120hZ? You seem to be spanning quite a large price range too. Two 780Ti's that weren't Phantoms would be my choice.

Just because you have have the money, doesn't mean you should spend it.

As asked by JR23, what exactly do you use your PC for?

What ever you DON'T get anything that will add up to 4 GPUs for gaming. That 2nd 690 for starters will only be about ~70% tops utilization due to scaling. Second you will have 4 very high powered GPUs and only 2gb of usable memory, even though the cores could easily handle 4k gaming 2gb of vRAM will hold you back, you will barely squeak by at 1440p with more advanced games. Next it would be a massive power hog and get very hot. You will always be better with one VERY powerful GPU and 2 of them tops. Once you start hitting 3 you really start hurting your price for performance. A lot of higher end games are using 2gb easily at 1080p now.

Hell BF4 can easily use 3GB of vram on 1080p with max settings and 4x MSAA.. I had to lower settings just so windows wouldn't prompt me about no more vram.

My two GTX 690s @1600p maxed on BF4 have no problem beating two of my 290Xs at the same settings.

Having said that the GTX 690s are not and have never been a serious option for any resolution above 1600p

The other thing to remember about the 690s is they are not a good option for anyone looking to plan ahead as monitor resolutions are going to be increasing in the near future with 4K becoming more mainstream.

I don't see how this relates to my post.. i only talked about how i run out of vram with 3GB being used nearly instantly

GTX 690s use 2GB which is a shame as it means they have never been any use for resolutions above 1600p.
