I7-6700 vs 8700 for new build?

[Alpha1tango]

Intel Core i7-6700 or i7-8700? Both non-k.
AMD Radeon RX 590 (once released)
Samsung 960 Evo 500Gb
Seagate Barracuda 7200 2TB 
Next kraken M22 120mm AIO
Micron 16ATF1G64AZ-2G1A2 DDR4 2x8GB
NZXT white H500i

I'm building my new PC. I have a Dell Xps 8900 with an i7-6700. I was wondering instead of using the 6700, I can sell the dell pc and get me a i7-8700. Upgraded specs from the 8700 and now i  can now use a z370 board. I don't mind using the 6700 but would like to have this build for awhile. My question would be is it worth the upgrade with advantages of upgraded performance and be able to use the z370 boards.  Any help is appreciated. Thank you!

 

P.S. I'm using 16gb of memory that was used in the dell XPS until ram prices drop hopefully in 2019. I'm pretty sure it would work with a z370?

Since you already have the CPU you should just get the other parts, and if the performance isn't up to your standards you can upgrade the motherboard. The ram would still work with the new motherboard.

If you are buying non k version I would get a b360 or h370 motherboard tbh. Also with the Intel supply issues I am not sure if trying to buy an i7 8700 after selling the 6700 is a super good idea.

The 8700 will give you.

Higher boost and base clocks

2 more cores / 4 more threads

access to the new chipset

 

Depending on price difference the 8700 is going to be the better choice.

8700 is a better choice, go with a nicer b360 motherboard since you're not overclocking. Also, depending on the power of the 590, the 590 could bottleneck the 8700 but we'll have to see.

Well as far as supply issues. I'm planning on selling the dell Xps 8900 pretty cheap say like $300-400. No ram. So that should sell fast and grab the 8700 from Amazon or some place. As far as motherboards i wild enfitbely looking into the b360 and h370.

I hope it doesn't bottleneck. I think chances are slim but we will have to see.

I'm not sure if this is a good reference point but the the GTX 1060 with GDDR5X memory that just got released and I guess you can compare that against the 590 since it was made to compete with the 590. Probably isn't but just an idea
