I'm thinking about upgrading both my processor and GPU to the Ryzen 1800X and the GTX 1080 Ti. I'm new to PC building and I'm trying to learn a lot more. I read online where someone said that mixing an Nvidia GPU with an AMD motherboard and processor would cause it to not reach its full potential and that AMD motherboard work better with AMD GPUs. The reason I'm not waiting for Vega is that I've currently got a GTX 670 and I want to upgrade really soon.

Would the Ryzen 1800X be a good combination with the GTX 1080 Ti or would there be compatibility issues? Or would they work fine together? I just don't want to gimp my PC.

This isn't true. Any combination is appropriate. With a 1800x you're going with the top of the line CPU...

Completely false. You can use any video card with any GPU. New Ryzen CPUs will not bottleneck the 1080ti. If anything, the 1080 will be the bottleneck and the Ryzen 1800x is OP for most gaming needs.

Well, I've got $250 in my wallet on Amazon so I thought getting an 8c/16t processor for $250 would be a pretty good deal. I figured since games will start using more cores in the future I would be well off with a processor like that. But do you think I would be better off getting the 1700X? Or just forget Ryzen completely and get the i7 7700k for the single thread performance?

This isn't true. Any combination is appropriate. With a 1800x you're going with the top of the line CPU, so you'd logically want a top of the line GPU. Since you're not waiting for Vega, which I imagine will be in line with the 1080Ti anyway, I'd say go for it. I am waiting because I have a 4K Freesync monitor, and that is going to need an AMD GPU. There's plenty of reason to mix and match, just don't mix a weak CPU with a fast GPU or vice-versa.

You got some magically benchmarks nobody else in the world has seen?

Unless you're video editing or something similar, there's absolutely no reason whatsoever to get more than a quad-core processor. Most games don't use more than 4 cores, a few don't use more than 2, and very few scale well with 6 or more. There are diminishing returns for your money. You could spend $400 or so on a Ryzen CPU when a cheaper 7700K would perform almost as well, with the added benefit of having much faster single core speeds. There are reports of people overclocking the 7700K to over 5.0GHz on air. I personally have my 4.0 6700K overclocked to 4.6GHz. Benchmarks are one thing but unless your programs can unlock the full potential of your cpu you might as well just get a quad core with faster per core speeds. (WoW for example uses ONE CORE for the most part and 3 kind of, and 4 cores/threads not at all) So overclocking I got 20fps more with that 600MHz. That should be a factor in your purchase for sure.

It also depends on what resolution you play at. My CPU is MORE than enough for anything at 3440x1440 @ 100Hz, a 1080 Ti is only recommended for my resolution and above. I plan on getting one myself, but for 2560x1440 a 1080 is perfectly fine (unless you're running 144Hz) If you're running at 1080p you shouldn't need anything more than a 1070. That should also be a factor in choosing your stuff.

There's no point in building a 4k Gaming beast if you're playing at 1080p.

Further investigation. The 7700k isn't any worse than the 1800X. 7700K is a full GHz faster core speed. So like I said unless your programs can handle the 8 cores/16 threads of the 1800X, you're throwing away about $150.

Excerpt from Tom's 1800X review...

"It’s hard to recommend the Ryzen 7 1800X over Intel's lower-cost quad-core chips for gaming, especially given the Core i7-7700K's impressive performance. That's not a knock against AMD, specifically. After all, we say the same thing about Intel's own Broadwell-E CPUs. High-end Kaby Lake processors constantly challenge pricier competitors, and the flagship -7700K sells for $350. Even after down-clocking the -7700K to 3.8 GHz, it still beats Ryzen 7 1800X in nearly every game in our suite. Those issues would only be exacerbated on a Ryzen 7 1700X, which operates at lower clock rates."
