Well, a i3 6100 and a FX6300 cost about the same, CPU to CPU. And the i3 will tend to beat out a FX, but not by a huge margin: they both perform fairly close to each other in gaming right now. An i3 has faster per-core performance. A 6-core FX will win out on things that can multithread better (not so much most games right now, but if you do movie encodes or streaming or anything like that).
That figures on the hyperthreading in a Core i3. That basically lets Windows (and other programs) think there are 4 cores available, even though there are only 2. The HT cores will give about 40% of the performance of a real core. That doesn't really impact a i3 vs a FX, because that's already baked into those benchmarks, but it does become interesting when your comparing a i3 to i5 to i7.
And yes, you can upgrade an i3 to an i5 (or i7) later on, of the same generation (so another Skylake or possibly Kaby Lake).
That being said. If your getting a cheap H110 motherboard to drop that i3 into (so you can make it all fit in your budget), that isn't exactly something I'd recommend going back and dropping an i5 or i7 into later on. For starters, now you've spent an extra $120 on your computer that you didn't have to by virtue of having had purchased 2 CPUs for it over time. Second, when you do decide to upgrade it later on, your probably going to want whatever the latest chip is (Coffee Lake / Cannonlake / Zen / whatever), and your going to be stuck on Skylake/Kaby. Which, to my third rationale against it - either you go used, or you'll still be buying that Sky/Kaby at full retail (and possibly more than you could buy a faster Coffee/Cannon/Zen/whatever with more performance) - just because it won't be stocked very much and CPUs don't get cheaper as they get discontinued.
The general rule is, don't build something lesser now planning to upgrade it later to what you want, because that will cost a lot more money than just building what you want now. And if you can't afford what you really want, then build the best you can with what you got - but don't build it planning on upgrades later, build it with as much performance as you can pack in there now.
Feature for feature, a AM2+ motherboard runs about $20-30 less than a similar H110 (and a lot more than that for a Z170). AM2+ also uses DDR3 ram, versus DDR4 - now if you are buying new RAM, right now that costs about the same, but more people have DDR3 laying around than DDR4, which may or may not make a difference in this build. Even $20 is a significant savings on a $500 budget, and that can go directly into things that net you better performance: a bit better video card, a bit bigger SSD, etc.
For those reasons, I'd recommend a FX6300 instead of an i3. Either will work, but I think in that budget range, the FX still makes sense.
no no, im not planing for an upgrade later on, im trying to make it the best for this budget, i was just pointing out some good points so I know which is best to pick.
wouldnt an i3 has better upgrade ability than the FM2+ socket? I could squeeze all this in for exact $500 Would it worth the extra $ for the i3 rather than the X4 860K or 880K? any bottle necking when it comes to GPU ?
The upgrade path on a Core i3 is to later buy a Core i5 or Core i7 that you could have bought today. So while it's nominally upgradeable, the upgrade path really isn't interesting unless you expect to have a much bigger budget in a couple of years or so.

FX8300 is best for that purpose. i3 is falling more and more behind more core CPUs with every game released. 2 cores aint cutting it any more in 2015/2016. It will only get worse going forward.
FX 83xx wernt good 5 years ago when everything was single threaded. Now look at games and you will see that its completely turned around and is now up there with 200-250$ i5s.

You only oick i3 if you exclusively play old games and have no interest whtasoever in anything mid 2015. and later (DX12/DX11.3(aka DX12 proxy))

Only way you could save 20$ is going with FX-6300+760G+stock cooler. Do you even realize what you are suggesting?
Won't even address the rest of your "points" since it just goes along in the same spirit....
