This 860K purchase could be one of the worst purchases I have made in a long time.

It would be even worst purchase if you would bought the Dual Core Pentium.

The 860K under DX-12 games will be more than fine for your second PC system.

I plan on buying both sometime in the next week or month. I'm still debating between nonref 1080 and dual Polaris xt for my 6700k build. I would like dual GPUs for light 4k gaming.

Both are wrong choices. GTX1070 SLI AIB is better than both for 4K gaming.

Also have a budget of roughly 200 for a new videocard for my second/spare computer I use for browsing and light gaming but looks like I am severely limited by my cpu.

Unless you know for sure the games you will play on this rig are GPU-limited, do not bother buying anything above the $100 GTX950 I linked. Not sure why you are so paranoid about rebates. I've gotten 99% of all my rebates over a decade. Just follow the instructions exactly and send the rebate before the post-marked date.

860K isn't even fast enough for a GTX950. Asus Strix 950 + 860K = CPU bottlenecking! Just telling you the truth, save yourself $100 towards a future rig upgrade:

If you spend more than $100 on a GPU for this 860K rig, you are wasting $ straight up.

I'd wait for Polaris and see what that brings. Should bring some nice improvements in your budget range of $200

RS, I don't have a SLI motherboard so that leaves me with a choice between the baddest 1080GTX I can find, or dual Polaris XT's. I'm reading that Polaris XT is going to ship with 8GB GDDR5X and I'm expecting to be surprised with whatever they show at computex. I doubt its going to be a 300 dollar weakling with all the highend RAM on board. Hopefully AMD doesn't disappoint. Also, my motherboard has two PCIE lanes with only crossfire supported. I think they are two 16x PCIE 3.0 with the second lane notching down to 4x if I am right. Would I lose performance crossfiring with this motherboard? It's a ASUS z170m-plus (which I really happen to dislike).

I don't have a printer and there are no kinkos anywhere near here for miles. It wouldn't be worth my time. I have also decided to pass on the $200 GPU and focus on my primary build which leaves me with close to a grand to spend on the GPU alone. Thanks for your help btw.

16/4x crossfire has minimal impact on performance, but P10 will likely be slower than a 1070, and 1070 should have way better overclocking headroom. If you have a 4K monitor and $1000 GPU budget, you can sell that mobo, or buy 1070 SLI and a new mobo. Wait for benchmarks if 1070/1080/1070 SLI vs. 1080 SLI.

I see. Thanks for the advice though I doubt I can move my motherboard at even close to what I paid for it considering I have no paypal and odds of selling local are very slim. I'm thinking about putting it into a possible third setup but I am unsure of which CPU to use for that considering its a Z170 board and I would like some kind of overclockability and get my money back. But if I were to do that, I wouldn't be able to purchase SLI. In case though, does anyone think two 1080's in SLI would bottleneck my 6700K with 32GB 2133 RAM?

EDIT: Sorry bad journalism. It has been confirmed by AMD there will be Polaris 11/10 AND Vega 11/10!

What do you guys think I should do with a budget of $1000-1100 to get my PC ready for QHD or QFHD gaming?

Here is my setup:

Corsair Air 240
Corsair RM750x
Asus Z170m-plus
Intel i7 6700K
Corsair Vengeance (2x16) 32GB 2133
Intel 540 1TB SSD

Someone help me with my build! Thinking about dual 1080/1070 SLI or Vega 11 xfire... Need to know if my PSU can handle 1080/1070 in dual SLI and if the GPU's would be bottlenecked by my CPU/RAM.

The CPU and ram should be fine, and your PSU should be fine for 1080 SLI if you don't OC too much. We don't know much about the power requirements of Vega yet though, afaik.

Thanks mod, but what do you mean by OC too much? Are you saying I could run out of juice while OCing or that my PSU could eventually fizzle out quickly? What if I were to load my computer with two more SSD's and three HDD's?
