Sirmike :
Yeah I feel you on the mobs and processor ... Here's one of the boards I'm looking at
https://www.asus.com/us/Motherboards/X99DELUXE/
And a i7 5930
For a case I really like nzxt h440 in white I will prolly find one like that but size large
Cable management cable kit in white and black
2x R9 280/295/380/390
Power supply seasonic snow silent 1050
http://www.seasonicusa.com/SnowSilent%20Series.htm
With some AIO water cool stuff white and black memory
Some SSD hard drives etc ...
What I want to do is be able to use the eyefinity system to make sure it's what I want .
I would like to get the bigger 8 core i7 it's real expensive ...
I think the processor I'm planning on using will perform well .
Choosing your processor is, in my opinion, almost completely reliant on your graphics setup.
The advantage of an i7-5930K is that it has many PCI-Express lanes, meaning it can control multiple cards much more easily than an i5, an i7-4790k or even an i7-5820k. However the 5930K, even though it boasts more cores, has a lower clock speed than the i7-4790K, and so isn't really any more remarkable in performance in gaming. Plus, the i7-5820k, i7-5930K, and i7-5960X are all X99 processors. The special X99 motherboards and new DDR4 RAM will be more expensive than a more common system with a Z97 motherboard and DDR3 RAM.
The advantage of an i7-4790K is that it runs faster. It's only a quad-core versus the hexa-core 5930K, but the i7-4790K makes up for that in gaming performance by boasting a significantly faster clock speed. And in gaming, you need fast and strong single-core performance. Besides, all Intel desktop processors except the current i5 series use a technology called hyper-threading, where Intel can get a quad-core processor to perform like an eight-core processor. Like I mentioned, the processor, motherboard, and RAM on a Z97 system will save you a few hundred bucks. But you have trouble running multiple graphics cards - each card is limited to a certain bandwidth, and if you want to add any more PCIE cards, there goes your performance.
You could go for an X99 motherboard, for sure. The Asus X99-Deluxe is a good one, although let's also keep in mind the X99-A as a lower-cost alternative. And the whole point here is to grab a 5930K so that we can run two cards at maximum efficiency. Couple that with 16GB DDR4 RAM. Now, for multiple cards, the R9 390X suddenly becomes a viable option. Why? Because when you run two cards in Crossfire, the memory is not added to each other. If you crossfire two 4GB video cards, you don't end up with 8GB video RAM. You still only have 4GB because the two cards must have identical RAM. And for once, the bloated video memory comes in handy: now we not only have the processing power of two graphics cards, but also the video RAM of two graphics cards. AMD, however, does have a glaring flaw when it comes to multiple graphics cards, and this flaw is more unique to AMD and Nvidia is not quite so affected by it: AMD has demonstrated in the recent past a distinct lack of support for Crossfire drivers and profiles. This means that you can only use one AMD card at a time. Nvidia, in the meanwhile, has shown a far more consistent support pattern and is considered to be much better about day-one driver releases, etc. There have been far fewer complaints about SLI support than there have been on Crossfire support. So, we can look at the Green Team's options. Although the GTX 970 and GTX 980 don't have the inflated memory buffer, they can still offer impressive performance through their fast memory clocks, newer architecture, and higher number of processing units. And, like I said, the GTX 980 Ti has proven itself to be an excellent choice, especially in SLI.
But, two other options lie here, and they would be likely more cost effective and may not compromise any performance.
Both options have the same basics. Instead of grabbing an Asus X99-Deluxe and an i7-5930K, you could grab an Asus ROG Maximus VII FORMULA or Maximus VII HERO and an i7-4790K. You could use 16GB G.Skill Trident X or Corsair Dominator Platinum RAM - or, since it's DDR3 and we've already saved a ton on the CPU and motherboard, you could push it further to 32GB RAM. Now here the two options diverge. Firstly, we know of the already-released R9 295X2. It's the dual GPU based on AMD's Hawaii cards, the R9 290X. The advantage of having a 295X2 is that you get two cards for the data cost of one: you don't need to use up extra PCIE lanes from the CPU to run a 295X2 properly. And a 295X2 comes with a liquid cooling system installed, which you have indicated you want to use. Secondly, there is the upcoming Fiji dual-GPU, which will be the successor to the R9 295X2. We don't know what it will be called and it will not be released until this fall. But it will use HBM and it will be a very, very fearsome beast indeed. Of course, the crux of those two options is that they rely on AMD Crossfire support, which may or may not be reliable in the coming future. So the GTX 980 Ti is also an option, or maybe even the R9 Fury X if it can stand up in the benchmarks.
The R9 Fury X (MSRP $650) will be released June 24th; the GTX 980 Ti (MSRP $650) has been released for a few weeks now; and the dual-gpu Fiji card (MSRP unknown) will be released in the fall. The R9 390X (MSRP $430), R9 390 (MSRP $330), and R9 380 (MSRP $200) will come on Thursday, June 18th. One clarification, as before today some of my information were reliable but unconfirmed leaks: the R9 380X has not been formally announced, and the beefiest R9 380 models will have just 4GB video RAM.
