I'm having a hard time choosing between these graphics card. I want to max all settings in 5760x1080 and 2560x1440. I also want the graphics card to last me in the next 3-4 years. If you had this to make this decision. which and why?

GTX 690 SLI. Three year warranty + better than the other two.

Take a look at these charts, and it is clear that Titan SLI is the best choice:

There will be times that 2x 690's will do better, but Titan SLI will be much more consistent and with more vram, it will not run into vram limitations that you may get with that much horse power at high resolutions.

quad sli doesn't scale better.
7990 is good choice but the with new drivers only as reviewed by tom
but best scaling would be titan sli

price is 2k$ that should be also considered why not wait till gtx 700 series maybe 780(titan LE) sli scales better & cost around 1200$ as per speculation

If you want the best solution, regardless of price, go with the GTX Titans in SLI. The 690 is a horrible solution for anyone playing on high resolutions because it only has 2GB of effective vram. Also, as shown previously, it is a weaker solution than the Titan in terms of raw performance. Also, it's more taxing on your power supply, has a less efficient air cooling system (resulting in crappier overclocking), does not have GPU Boost 2.0, and you're out of expansion options, considering you're already in quad SLI and with 2 Titans you can still get 2 more.

The 7990 is superior to the 690, but I really don't think you'll want to deal with Crossfire, especially 4-way Crossfire. All previous arguments hold except for performance. I have not seen much on the 7990, but just look at the Aries II and tone the benchmarks down a little to get an idea. To make things easier for you in the future, go off of the following list when comparing GPUs:

- Price per performance
- Overall performance
- Vram
- Expandability (how many cards can you run in total?)
- Power consumption
- Cooling solution (if you want to overclock, this is essential)
- Multi-GPU Scaling
- Bonuses/Gimmicks (GPU Boost 2.0 is an example)

Does this still hold true? I am in the similar situation and I was leaning toward the 7990 quad fire because I will only use it for gaming with 5780x1080.

Ok so 780s? what about 7970 trifire? Also can the 780 in sli do 3 or 4 monitors? in hdmi? im using monitors with only hdmi

Also the 780s only has 3gb the 7970s ghz has 6gb of vram i know vram isnt the most important thing but why should i go for the 780 not trying to be an amd fanboy but I heard the 7970 works better with 3 or more

7970's have 3gb of vram, or are you talking about some special version?

Also 3-way crossfire does not improve anything with crossfire. There was a review done a few years back on this site, and they tested 1 game in 3 way crossfire, and it appeared to help, but as further tests have shown more recently, crossfire does not get better in 3-way. What can happen is the CPU can bottleneck, and sometimes the bottleneck and help, but that isn't something to be relied on, or even something you really want.
