+ This is only for a gaming/browsing computer which I'm hopeful will last 5+ years (mb/cpu at least)
-1xPrimary monitor for gaming 2440 QHD + 1xMisc Pandora/web browsing 1920 monitor.
-My budget is 2k (I'm not sure if it's worth going over 1500)
-I would prefer not to overclock much if at all, and doubt I'll do 4k gaming this build.
-I am waiting for the Geforce GTX 2070 series instead of buying a 1080 now.
-Max simultaneous load would be a really high demand game like Hitman 3 Max setting + 20 webpages+pandora/itunes and maybe some more background non memory/graphics intensive programs. (I do not stream games)

(I realize the 6850k is way more than the 6800k, but if I was to go x99 that is the cpu I would get)

+ My current thoughts are:
-MB/CPU - MSI SLI Plus x99 + 6850k@ 4.2OC or MSI SLI Plus z270 + 7700k @ 4.7OC
-GPU - GTX 1070 x 1 + 2070 when its released (cost of 2070 not part of this budget)
-Ram - 16gb (2x8) 3600 G-Skill Ripjaws OC'd to 3k-3200
-Storage - MyDigitalSSD BPX (480GB) M.2 + some $40 1tb HDD
-PSU - EVGA Supernova 650 GS
-Cooling - All air | Noctua NH-D14 (assuming RAM clearance isn't an issue)
~I don't see a need for liquid with low OC and good airflow
I care only about performance not a "hot rod"


+ Primary Concerns:
-Any general recommendations are welcome (This is my first build)
-I am trying to decide between 4 core/6 core CPU's (Most likely I will never use SLI)
~Is it worth getting 6 cores and an X99 MB if I'm not getting 4k gaming (assuming the GPU isn't the bottleneck)
-Would I be able to run the 1070 and 2070 in SLI or would the new architecture conflict?
~Better to use 1070 for 2nd monitor or save for backup after 2070 is release?
-Do I need more than 650W PSU if I add a 2nd GPU down the line?(I know I said I probably wont but I may change my mind 2-3 years down the road)
-It seems games are going to be favoring 4 cores for awhile from what I've read, and the fact current games are spotty on sli support (and probably will be for a few more years) makes me think it's better to wait for the 2070 series rather than get a 2nd 1070.
-For my needs (2440p gaming) is there any reason to upgrade past a z270 chipset.
~From what I can tell the only big difference (Since it's a gaming computer) would be if I wanted to utilize SLI and have 40 pcie.
^Is there some other major performance benefit I'm not seeing for my purposes?

+Sorry if this turns into another "7700k vs 6800k"ish thread, but all the ones I see are for rendering software/steaming games and I wanted some more personalized responses and any general advice.

Oddly enough you needs a better GPU and weaker rest of computer to run 4k 60 fps. than even 1080 100fps. Why get a 6850? A 6800 is a good bit cheaper and the only real difference is PCI lanes for sli. You're missing plan c. Wait 3ish weeks and buy a 8core/16thread AMD CPU for less than the 6850(supposedly one for less than the 6800 as well) and not have an issue for a long time.

Well the 7700k would be the better choice, in terms of price, becasue its powerful enough for gaming
no 1070 and 2070 sli is not possible, you need the same cards for a sli, and the fact that one single powerful cards is much better than multiple cards, and still games have trouble on sli setup, well can you tell me where you are planning to but the parts from, online or from stores in your area, if online maybe i can build a pc on pcpartpicker

Regardless of what you pick to build I would wait for Ryzen to launch unless you need a PC ASAP. I built my nephew an i7 6700k @4.4Ghz last week and it kind of killed me knowing Ryzen was so close. I felt I could no longer wait with his build as it was a promise I made him years ago that I would build him a new PC when he joined the marines and he recently got to his long term command. I could of bought him more CPU for less money had I been able to wait if the benchmark leaks are to be believed (and I am starting to think they are legit). If Ryzen delivers on it's promise I would consider an AMD build over intel. At the very least Intel will have to respond by lowering their prices. Either way you win and pay less and potentially get more CPU for your money. I would not upgrade ATM unless it is 100% absolutely necessary. By waiting one month and the price performance landscape will change drastically.

i really hadn't considered amd, but if it promises what is said I think I would change my plans to the R7 1800X and get ready for a 4k instead of 2440p setup once the GTX 2070 comes out and do an SLI.

8 Cores (basically auto overclocking supposedly) already 4ghz turbo for $500? 12gb gpu x2 for ~$700? What could go wrong.

Thanks for bringing that up, tired of this old ass laptop, but I agree it looks worth the wait.
Plan C.) it is.
Next question is will Nvidia 2070/2080 even need sli for 4k....Only time will tell I guess.
Appreciate the answers all.

Biggest issue is in several new titles SLI give exactly a zero % gain. Many are in the 15-20% range. I'd buy a 280/1080ti(if it actually comes out) as it'll actually get it's performance everywhere. SLI does nothing for video rendering and many games.

While SLI does have short coming I don't completely agree with all of that, especially when gaming at 1440P-2160P like myself. SLI has always had draw backs in support and scaling has never been perfect; however, if your rig is properly configured and you can be patient with drivers/support when SLI is supported I do find it to be beneficial for those like myself who play at high resolution with max settings, filtering and AA. That said though unless your willing to accept the short comings/slow support and you game at high res, max setting ,16x by 8x filtering AA then SLI is likely not the best investment. Regardless in the case above he couldn't SLI to different cards anyways.
