So I'm looking to switch my amd 6300 and gigabyte ga-990fxa-ud3 with an Intel setup.

I want the Intel setup to last a s long as possible without mobo and processor upgrades

Should I go with the 6700k or 6800k?

Also need new mobo and ram suggestions. Need at least 16gb ram and crossfire support.

I have the Rx 470 8gb by sapphire and a 650w PSU.

Lowest prices on decent hardware is my biggest concern, though I'm leaning towards the 6800k.

I suggest the 6800K due to most of the 2011v3 motherboards can hold upto 128GB. Cannon Lake late next year will be 6 cores which will become the stander core count.

I would go with the 6700k to be honest unless you have a pressing reason to get a 6800k (really multithreaded applications like compiling code, running VMs...). The single core performance of the 6700k is exceptional and with 8 threads I can't see any reason that it becomes obsolete any time soon. The 2600k is still a very potent cpu, the 6700k should be in 5-6 years as well.

EDIT: You don't need a special motherboard for crossfire, but are you going to be gaming? I'd much rather just sell your 470 and take the small hit now to get a GTX 1070, because crossfire is a pain. If you have your heart set on crossfire you should get a motherboard that has an x8 2nd pcie slot so you can run both cards in x8, otherwise you're going to have to take a performance hit at x4. Also I wouldn't run 2 470s on 650W, you can but that's cutting it a little close.

Solution
What will this pc be primarily used for?
If it is for batch apps that are multithreaded, then the extra cores of the I7-6800K will be best.
You will pay more for the motherboard.

If it is for gaming, then the faster core speeds of the i7-6700K will be best.
You can OC a I7-6700K higher. 6800K will max out at 4.2 and a I7-6700k will max at 4.6.

Any new motherboard will have support for 32gb of ram or better.

You will pay more for a motherboard with sli/cf support.

I would not plan on dual gpu.
You may win synthetic fps benchmarks with dual cards, but
games play better with a good single card.
You will be more prone to stuttering and screen tearing.
some games do not support dual gpu.

Your 650w psu can handle a single card as strong as a TITANX-p. And even stronger single cards are coming.
