Im thinking to sell my old pc for a new one... i thinking to buy i7 5960x and 4way SLI 980 GTX with Watercooling Both.
What do u think they will bottleneck without cpu OC ?
I want to ask something else.. i dont know what cpu cooler i have to buy for the 4 way sli 980 gtx and the cpu and ram and mobo
fully watercooling.. what u prefer ?

I have one screen 27' and i want to play all games maxed out battlefield 4 call of duty crysis 3 metro last night . i want to get the most fps! i have now 780 ti and i want more . and cpu 3970x So why not just buy another 780Ti? That would be a much less cheaper option and would still keep you very much in the same range of performance.
Let me ask this: how many FPS are you seeing now? What is your goal? It would seem this is just a thread about choosing maxxed out expensive hardware without really understanding why or how or what differences you would see.
Also, you aren't going to see vast improvements going from a 780 Ti to SLI 780 Ti or even SLI GTX 980's. You might see some minor improvements with AA and shaders, but as it stands now, I'm betting you can play all those games on maximum and at good frame resolutions.

I agree, it's all a bit of moot point really, as 4-way SLI often works so badly. Here for example, is an actual 4-way 980 GTX review, and while there is a gain in some games, in others the performance with 4 cards is almost identical to what you get with 3. 3-way is certainly the absolute limit I'd ever recommend, and even then I'd be unlikely to recommend it, and only for extreme resoltutions.
It is a bit strange that nVidia seems to top out at selling 3-way bridges though, isn't it? It leaves it up to the manufacturers like EVGA to sell the fancy looking 4-way bridges.
EDIT: Anyway, sorry for derailing the thread everyone! The pedantic side of me just wanted to clarify that 4-way SLI does indeed exist, but that doesn't mean you ever want to opt for it!

Interesting since Nvidia doesn't sell 4-way SLI bridges; only 2 and 3-way bridges. I realize that you can technically SLI w/o a bridge being in place, but I guess I was misguided thinking it wasn't possible as 4x PCB cards; I have always assumed it was via 2x PCB/4x GPU.
980's are only single GPU/single PCB, so we'd be drawn to assume 4x PCB SLI as this example.
Still appears that there is almost negligible difference between 3 and 4-way on those charts (albeit, comparisons of 780Ti and Titan), which falls in line with most 2x and 3x SLI scaling and diminishing returns.
I'd still challenge to see what is needed that 2x SLI 980's would not be able to handle.

The difference between quad SLI and 4-way SLI I mentioned (2 x 2 gpu cards vs 4 x 1 gpu cards) is certainly how many motherboard manufacturers do it, and I'd have to assume nVidia accepts this naming scheme, seeing as it's used so often.
I'm afraid I'm going to have to disagree that 4-way SLI doesn't exist, as there are 4-way SLI reviews out there (not many, unsurprisingly), for example here, here, and here. Scaling can be a real issue, and lead to worse performance when moving from 3 to 4- way SLI, so I certainly wouldn't recommend 4-way SLI, but it does exist, and the 980 supports it.

4x SLI doesn't exist. Only 2x and 3x SLI. There have been plenty of tests done about the performance differences between them. I'm curious what you are playing that you think you need 3x SLI 980's for?
a 690 is two 680 on one board in sli putting two of them in a system will give you 4 way sli. There is nothing right now to do 780 or 980 4-way sli only 3-way
Am I missing soimething here? Are people conflating Quad SLI and 4-way SLI? Quad SLI is normally used, at least by motherboard manufacturers, to refer to two dual GPU cards put together (like two 690s for instance), while 4-way SLI is used to refer to four seperate graphics cards together. ASUS for example lists their X99 deluxe board as being capable of 3-way and quad SLI setups, while their X99-E WS board lists 4-way SLI.
The specifications for the 980 specifically list it as being 4-way SLI ready (as opposed to the 970, that lists only 3-way SLI ready), so I find it a little hard to believe that 4-way SLI doesn't exist.
