SLI and my woes

Hello i just signed up here hoping to get more involved in PC technology and news regarding technology advancements, news and just gaming in general.

With my semi brief introduction out of the way i would like to ask a question!. And i am sorry if this has been asked multiple times before but i couldn't find anything with my sort of description and this is a lot of money we're talking about here.

Alright so what i want to do is upgrade my GPU. I currently have a GTX 680 OC windforce edition. This card is still absolutely fantastic and has aged extremely well, i'd even go so far as to consider it a part of the family :). But i want more out of my system, recently i decided it was falling behind in some modern games. It still plays most modern games at 40-50 FPS but i would like to start gaming at 1440P and my GTX 680 just can't do that unfortunately...

My question is. I just watched a video of two GTX 970's in SLI in a few benchmarks go up against a single GTX 980 TI and to my surprise the GTX 980 DESTROYED the TWO GTX 970's in SLI. I was shocked beyond belief that such a card could output so much performance. And that got me thinking, is SLI really that bad of a system?.

Does anybody have any solid statistics for SLI and what games do and don't support it well? Does the GTX 980 TI really destroy everything on the market like i've seen? Should i buy two GTX 970's or a single 980 TI?

Thanks for reading my long and boring post :D

Check the list. But check the price too. The ti's are in a different league than anything, and yes, you can get nothing better performance wise.

Compare the 970 SLI to the 980 instead.

For the past 4 years, both AMD and Nvidia have been stuck at the 28nm node process when it comes to making chips. The fabs simply did not create the technology that both companies needed at the 20nm node.

So now the fabs have moved to a 16nm FinFet node, and created what AMD and Nvidia needed at that level to produce new chips. But the announcement that this process is now in full production was just...

But the announcement that this process is now in full production was just made yesterday. So it is going to probably be about June 2016 before we see any of those GPU's hit the market.

So back to the GTX 760 vs GTX 970 comparison... Both are 28nm GPU's. There were minor changes to the GPU over the years, but since they are both made at the same technology level, they are going to perform very similarly.

When the new video cards come out next year, they will be as much as 65% faster with the same number of transistors, and they will have new HBM v2 (High Bandwidth Memory) which will allow for as much as 32GB per video card, with memory bandwidths as high as 1.2TB vs the maximum of 512GB today. They should also be much more power efficient, and much like what has been going on with the AMD Fury line, the video cards themselves should be much cooler and smaller.

After reading everything I have been able to dig up about all of this new technology, and observing how the AMD Fury X and Fury are performing with HBM v1 memory, and knowing what should be possible by next June, my guess is that when the product lines start flushing out next year, for the money you would spend right now on any given video card out there, the same money this time next year should get you a video card that is 50% to 60% faster than the card you can buy right now.

So unless you must have a video card immediately, you are probably going to be much better off just waiting for most of a year.
