I am in the market for a new dual SLI system for primarily gaming at 1080. I am torn between the comments I've seen in forums:

For Z97
1. Regarding the some possible thermal instability of the Intel i7-4790K CPU.
2. That it's old tech, particularly going into 2015.
3. But also, that it's better/less of a headache due to solid drivers by now.
4. Cheaper than the X99/DD4 option
5. Less PCIe lanes(won't get dual SLIx16 for each card)

For X99
1. More PCIe lanes with Intel 5930K and 5960K processors.
2. But have read in several places that tests show no appreciable benefit going from 8x to 16x
3. Also hearing that X99 systems are not much faster, especially at today's prices.
4. May run into bio/driver/stability headaches.

I prefer to use a system builder like Cyberpower, but perhaps if I went with a Z97 system, I could build this myself. I've noticed that there's about a 500 dollar difference in getting the parts yourself at Newegg over having a system builder doing it. If I'm looking at around $5000-$5500 for an X99 system build and only about 500 less to get all the parts myself, I'm wondering if it's just worth the $500 to not have to deal with possible headaches?

Of course, if I go the Z97 system route, things will be a little cheaper by maybe $1000 less(system builder route) for a system like that. Even less, if I build a Z97 system myself.

I would like to know about people's thoughts regarding the Z97 system. Is it the better way to go at this time? Are whatever performance gains in the X99 not worth it? Going forward 2-3 years from now, will the apparently small performance gains in the X99 really amount to much for gaming. Grant you I either change out video cards within 3 years and certainly system update by 4 years. Do some of the concerns I have listed make any real impact at this point in early 2015. I will probably be buying within 30 days.

 
I can't find anything that a single GTX980 can't handle with a 60hz 1080p monitor. If you are after much higher frame rates and have the refresh rate to match, maybe an SLI config makes sense.

For a rig this expensive I would expect nothing less then a 4K monitor or a ROG Swift (2560x1440@144Hz)

With the budget, no reason not to use X99, performance difference is marginal, and the i7-4790k does tend to average higher clock speeds when overclocked, but you didn't mention overclocking. If you don't plan on it, then the 4.0-4.4Ghz of the i7-4790k is a good choice and the dual 8x config doesn't cause any sort of bottleneck for single GPUs.

 


Here's what I was generally looking at in a X99 system from PC Part Picker:

CPU: Intel Core i7-5930K 3.5GHz 6-Core Processor ($499.99 @ Micro Center)

Total: $4447.68

Here's the Z97 system(basically just the MB, CPU and MEM change out):

Not sure if trolling or being legit :??:

EDIT: sorry thought you meant 4k res lol
 


A lot of this is overkill. You can get 16GB ram for $150 that will perform the same. MB, you can spend $180 and a great one, or less. PSU, overkill to the max. You don't need 2 980's for 1080p gaming.$200 sound card, meh. Not needed. Onboard or a Asus Xonar for $40 will do fine unless you are gaming on $500 headphones, you'll never notice a difference. Why your OS is $400, I have no idea. Win 7/8 is about $100. Hope this isn't a troll build....
 


It's been my overwhelming experience that getting good components makes a world of difference in little to no headaches and stability. I have gone Corsair memory for some time and it has been perfect. Asus motherboards have never let me down, while friends who have bought other brands have had issues. While I can comfortably drop the 1500i PSU to a Corsair 1200i, I do prefer a sound card. The audio is vastly superior and I use Audio Engine A5+ speakers with their S8 subwoofer for gaming and iTunes/higher resolution HD tracks stuff. With regard to dual GPU's, I prefer to game with all the graphical goodies on, so being able to play at a good clip for the next 3 years of future gaming seems at least to me a good reason to have a dual 980 SLI. The Witcher 3 will be coming soon and I want to run that with everything on at a great pace. Games are only going to get more advanced in the next three years, so I want that extra measure of headroom in a dual 980 setup, even at 1080 resolution.
