Building a new system not sure what GPU to get Going to run a triple monitor system with 2 2K monitors and a 4K monitor Going to game only on the 4K monitor the other two are for youtube web-browsing etc.. i also do a bit of Graphic Design work that the two side monitors will come in handy for.

Looking at 2 GTX980 or a Single GTX TitanX -

2X Asus PB278Q -2K
1X Asus PB287Q -4K

First off, 2 GTX 980s is far more powerful than a titan x @ 4k.
Second, 2 R9 290Xs will get you the exact same performance as the 2 GTX 980s @ 4k for nearly half the price.

Unless he needs the highest performing single GPU solution, or has a low end PSU, NVidia is rarely the correct answer for a buyer in the USA right now.

amd is crap atm. their cards are not dx12.1, they produce tons of heat, bad driver support etc... no point going amd.
Your statements are wrong or only true in a few highlighted situations. I'll explain why.
jerdle is right about 1 thing: the process power of two 980 is like 20-25% higher, than a titan-x, but if the vram usage goes higher than 4gb, performance will suffer. Huge frametime spikes will occure until the textures are reduced to fit the 4gb framebuffer. all 2014-2015 games already use 3,5-4gb vram on 1080p and around 5-6gb vram at 4k.
I'd note that anyone who judges a gpu solution by pure process power will fail when it comes to real life performance.

AMD cards do not enjoy full hardware support of dx12, its only partial, so any other support for rastors etc is software supported as is any nvidia card before the titan-x and 9 series. This is going to be the case with any version of direct X just because of competition between AMD and intel/nvidia/Microsoft.

The r9 295x2 is undisputed king of 4k gaming for a single card, better than the 980 and any titan version, including X. Is it going to suffer some in dx12 gaming? Of course. AMD is playing catch up as usual. Dx12 is a Microsoft design, and Microsoft us an intel fan boy, and consequently nvidia. If it wasn't for partner companies like Asus, Gigabyte, MSI, ASRock etc who have partnerships with Amd, amd would be left out of the DX loop for the entire 2 years it'd take for the copyright to expire, so yes, amd is going to have some driver issues with dx12. These will be fixed, just as issues with dx11 took some time.

If you are demanding the latest and greatest, yes nvidia is the only choice, but if you just want to play, amd doesn't suck either, and currently no games written demand only use dx12, they will all play on dx11 standards, and more than a few will still play on dx9c.

In 4k gaming, nvidia comes in second.

what are you exactly talking about dude? First of all the 295x2 is not a single card it has 2 gpus . it's a dual gpu card so it comes with texture flickering, microstutters and other usual cfx issues and the possibility of bad cfx profiles( what usually happens). a single gpu is not comparable to a dual gpu card. The technically correct comparison would be titan-x sli vs r9 295x2.

The 295x2 ships with 4 or 6gb vram per gpu. The titan-x has 12gb. every time the card reaches the vram limit, frametime spike will occure , ruining the performance. as i said 4gb is totally insuficcient and 6gb vram is rarely enough for 4k ultra gaming.

The r9 295x2 is a SINGLE CARD that runs 2 gpus. It fits in a single pcie x16 slot. It's not 2 cards. Might want to read things before criticising. It's also an 8Gb card. Might wanna look that up too.

And when it comes to 4k gaming, the 295x2 is the strongest single card around. It matters not if it's dual gpu, its 1 card. If you want to compare sli to CF, do so running 2 cards.

The point remains as I said, the 295x2 is the strongest single card there is for 4k gaming

You still don't understand. First of all that 8gb listed on the specs are missleading, since it's a dual gpu the 8gb version is actually a 4gb card, because vram does not stack. I'm well aware of the r9 295x2 specs, it ships with 4gb ( 8gb) and 6gb ( 12gb) version as i already mentioned. and both versions are insufficient for 4k ultra gaming.

You can highlight single a thousand times it won't matter because it still works like crossfire or sli. You can put 2-3-4 gpus on a card it will still work as crossfire or sli. The scalin will be dependent on game, and you will also suffer from the well known cfx/sli issues. In 95% of games there is NO proper crossfire/sli support at release and if only 1 chip works the titan-x will smash the 295x2 into ashes.
