4-5 years worth of gaming with option to upgrade

[Tsikio]

So I've been looking into the debate of Z97 vs X99.

With the addition of DX12, and the somewhat noteworthy problems of OC'ing the 4790k (several claims that it would overheat and throttle down to about 3,7GHz regardless of cooling) i was wondering if bumping to ddr4 and 5820k would be wise in like a 4-5 year plan, maybe adding another GPU for SLI a year or two into its lifespan.

My current thoughts for the build:

Case: Corsair Carbide Air 540 Cube Case
PSU: Corsair RM850 (enough for SLI?)
Water cooling: Corsair Hydro H100i GTX
Motherboard: MSI X99 SLI PLUS
CPU: Intel Core i7- 5820K
RAM: Hyperx Fury 2666MHz DDR4 16GB kit (Overkill?)
GPU: GeForce GTX 980 Ti (Oc'ed version?) 6GB
Storage: 120GB SSD

This is supposed to be a build for 1080p - 1440p gaming at ultra-high over the next few years.
Any input as to why not go this route or why to go this would be much appreciated, also where i might be lacking/overkill.

Stuff i could use from my old pc(4 years old):
Kingston 1600MHz DDR3 16GB RAM (if i were to opt away from X99)
2TB 7200 RPM Harddrives (will probably use this in the new one either way)
XFX 650w PSU (for just one card, and upgrade with the new card later?)

I wouldn't buy a 980Ti. Pascal would be much faster.

How so? I've heard that the next gen line from nvidia will have very little improvement compared to the improvement from last gen. also wouldn't that make purchasing a new desktop kind of unnecessary? I would have to wait almost a year to actually buy it.

Pascal will be a massive improvement from current tech. To begin with, 1.2TB/s - 2TB/s bandwidth of 32GB HBM that, combined with DX12 and 8 way SLI, means a potential 256GB of insanely fast VRAM. There is a die shrink in FinFET tech from 28nm to 14nm. Also since the HBM is stacked the GPU is much smaller and thus less heat.

So if I were to wait for pascal which is like what, march/april 2016, i should just get the rest and hold off on buying the GPU? Assuming my motherboard won't bottleneck the new pascal.

 

[Icaraeus]

Pascal might even require a new motherboard and it may release late 2016 when Intel Skylake launches. This is because Pascal uses NVLink, probably only for servers, which is faster than PCI-E 3.0 and allows bandwidth allocation between GPU and CPU, much like how the PS4's architecture works in a way (except Pascal's HBM is much faster - 1.2TB/s - 2TB/s as opposed to on the PS4 where it's 172GB/s with 30GB/s reserved for CPU.)

 

[Tsikio]

Would the fury not work? wouldn't that offer about the same as the pascal, without the wait?

 

[Icaraeus]

Pascal is far superior to Fury. For one - Pascal uses HBM2, Fury uses HBM1. You can get Fury if you want but Pascal will destroy it.

waiting for pascal just to play 1080-1440p doesn't seem logical

 

[Icaraeus]

If you want to use 1080p there's no reason to use a 980Ti,

I would suggest getting a now and days setup. I just built a pc with a i7 4790k and it is running perfect with heat. I'am overclocked at 4.6ghz x45 multiplier, and from 1.1-1.3 volts. It is only hitting 32 degrees Celsius ( constant). If you wait for pascal I bet you its going to be a huge cost to performance. Kinda like ddr4. Not worth it in my book unless you are going to be doing video editing at 4k or graphics designing. 980 ti is a pretty good cost to performance i'am getting one as well. A non-reference one for me though
