I5 8600k or i5 8400 with my 1050 ti?

I was looking through forums of people saying that a 1050 ti will bottleneck an i5 8600k, but I was hoping it would ok until I can I get a better gpu in the future. Would I just be better off going for an i5 8400 instead of getting the 8600k and upgrading the gpu in the future?

Either of the CPUs will work fine with that graphics card. The 8600k might have a bit more muscle than what's strictly necessary, but it's not going to be much different than the 8400 for gaming so get whichever one you prefer.

If you have plans to upgrade the GPU card later at some point, it's probably wiser to go with the 8600k so you don't end up with a CPU that might not be as capable when paired with a higher tiered card later. Honestly though, either of those CPUs will work well enough with practically any 1000 series graphics card.

I don't think you will really notice a difference now, but in 2-3 years time that would likely change.
Compare an i5 6400 to a 6600K in some modern games benchmarks for a comparison. The 6400 still does ok in most games but is starting to struggle in others. The 6600K still games very well in almost everything. Those are approx 3 years old now so anyone who has been gaming with either got a good run out of it so far but the 66000K should last a bit longer yet.

I'd expect the situation to be the same for the 8400 vs 8600K in a few years time. I wouldn't bother with the 8500 or 8600 though as there is not much benefit to them over the other 2 choices (8600K for performance, 8400 for price)

There is no bottle-necking either way. People nowadays are using the word 'bottle-necking' too liberally without good reason.
There is not much difference between 8400 and 8600k, UNLESS u plan to get a good cooler and apply a massive overclock on the 8600k.
Total cost of 8400 is lower (cheaper processor that comes with fan, B or H series mobo chipsets)
Total cost of 8600k will be significantly higher (pricier processor, need to buy good quality cooling, Z series mobo chipsets required for O'C)

Actually, there are differences other than those outlined.

For one thing, the single core boost of the 8600k is 300mhz higher, at 4.3Ghz rather than 4Ghz.

The all core boost is 300mhz higher, at 4.1Ghz rather than 3.8Ghz.

You might not think 300mhz is very significant, but try running a CPU at 0mhz and then at 300mhz, and see how significant it actually is. An extra 300mhz on six cores can translate into a lot more muscle under demanding conditions.

People spend a great deal of time and money trying to gain an extra 300mhz out of their overclock, and I can promise you that 300mhz CPU clock speed will net you far more of an increase in performance than any attempt at overclocking memory or tightening timings will ever provide. And people go through hair pulling, teeth grinding endeavors trying to do that. So, 300mhz does matter, at least somewhat.

Also, obviously the 8600k can be overclocked, which may net you an extra 300-500mhz (Or more if you're willing to push the envelope. I don't recommend pushing it more than maybe 4.7Ghz for a daily driver, but some folks definitely do it.) resulting in potentially an average estimated gain of about 600-800mhz above what you could ever have with the i5-8400. 600mhz difference on the same architecture can definitely be "felt" and will translate into recognizable performance.

So that alone makes for three good reasons why you might want to choose the 8600k instead.

But if you do go with the 8400, it's not going to "hurt" your performance either. It WILL still pair very well even with a high end card. Just not AS well.

You will not need to overclock the 8600k with the 1050 ti. You MIGHT want to overclock the 8600k later, if you get a higher tiered card though.

And if you have any plans to overclock, at all, you'd best plan to also purchase a really decent CPU cooler. I would look at 140mm models if you go with an air cooler. 280mm models if you go with water.
