The i5 is a quad core. Each core is around 60-80% faster than each of AMD's cores.
The FX is an 8 core CPU. However, when you're running all of the cores, there's a penalty to the performance of each core, because they have to share resources. It varies, but 10% is a reasonable estimate.
4 x 1.7 = ~6.8
8 x 0.9 (module penalty) = 7.2
I can see, in some situations where you can fully, 100% utilize all of the FX's cores, it being faster than the i5. In anything that uses fewer threads, the i5 could be as much as 80% faster.
The FX CPU will draw at *least* twice as much power doing the same work as the i5. It will also be on an older motherboard/chipset that doesn't have modern connectivity, such as USB 3.1, M.2., etc., which certainly helps to make the case for the i5.

It's not even a contest anymore. i5 skylake will run circles around an 8350. if you asked this maybe like... vs an i5 4460 or 4590 a year ago; there may be some merit of one versus the other, but unless you got 2/3rds of the AMD build already sitting on your desk it wouldn't be worth it to build AMD from scratch right now.

Investing in the AM3+ platform when it's dead in the water makes no sense whatsoever. If you're building from scratch, the 6500 is the only way to go.

Do you mean Crossfire? If so, the FX-8350 doesn't have an integrated GPU, and even if it did, that's not how Crossfire works.
Stick with the 6500.

I would disagree there.
I bought and configured last week a 8370 with a Gigabyte GA-990FX Gaming, and the latter has all the new stuff you're mentionning: USB 3.1, USB c, M.2, ...
I switched from a Core 6600@3.2 to this nice 8370 and I really can see a difference. I didn't want to spend too much but I wanted to see an improvement over my old config, and that's what I got. The 8370 can handle anything I throw at it, and I can still use my computer when overloaded. Really happy with my rig right now, it's more than enough for me. A i5 of i7 wouldn't have made me happier, but clearly poorer

^ 3rd party solutions are generally not as good as native ones, but I'd be nitpicking if I tried to use that as an argument against FX chips. It's a salient point, however, that you are not going to find boards which are as inexpensive on AM3+ with the same features, because of all of the 3rd-party controllers needed to equip it with these features bring up the price. By the time you've bumped up your power supply size a bit, purchased a 3rd party cooler, and spent a bit more on a motherboard, you might have paired a Skylake i5 with an H110 board and gotten a cheaper, faster, quieter, less power hungry PC.

My rig costed me way less than any i5 solution. FX was about €180 and the MB was €150. Had to buy some DDR3 RAM since I couldn't use the ones from my old config but it would have costed me more with an iX.
As for the power supply, I'm still using the same 650W and it's perfectly fine with the new processor.

Well, costs will vary from region to region.
On Newegg, the most commonly used US retailer, an FX8320e is currently $160, while you can get a Skylake i5 for $190. Considering you can save $0-20 on a power supply, $0-30 on a cooler, and $0-30 on a motherboard, an i5 comes out ahead when buying in the US.
My entire i5 PC, including a discrete GPU, draws only about 175w under load at the wall. I picked up my 400w platinum rated power supply for $25 US - which probably wouldn't be enough for an FX CPU.
If your region has significantly better pricing on FX CPUs, they can be a decent value.

there is a way to crossfire an APU with an GPU via crossfire but I have heard it is very inconsistent and most of the time drop performance.

just checked, a i5 6600K (K would be best I think)is €260, €160 for 32GB RAM (I know, that's a lot, but I'm just comparing with my 32GB DDR3 I got for €100), add at least €170 for the MB (Asus Z170 Pro Gaming for ex) and a nice radiator Noctua NH-D15S for €80 and well, it's a bit more than my rig alright.
Certainly faster, but like I said, the FX was within my budget, and it's totally up to what I'm doing with my computer. I know I'll be ok for some years again

I would argue that a 6600K + $90 cooler is pretty silly, when an i5 6500 beats FX-8xxx CPUs in nearly everything even without overclocking. You'd get, what, an extra 25% performance by spending an extra $60 on the CPU, $90 on a cooler, and $130 on a motherboard?
It's a false comparison, and there's rarely any value in overclocking these days. It's more of a hobby, because the extra money put into components to support overclocking is usually more than just paying for faster components.

hello
I choose the 6600K because the i5 6500 wasn't available in the store I used to go to, but it's back on sale at €240 now.
You're right, the 6500 beats the FX in almost everything, but still, the FX is less expensive and still a really good processor. I have setup my rig two weeks ago and haven't had time to really really fully test it, but my video encodings went smoothly, games run all very well, Windows is fast, everything is peachy. That's what I wanted, that's what I got
Oh, and I don't overclock. No need yet. I have the right mobo, the right power supply, I might do that later but so far, no real need.

True, but the OP doesn't have an APU. The R7 250 is the best dedicated GPU you could Crossfire with an APU, so it's hardly worth the trouble.

I disagree. I'm very happy with my new 8370-32GB RAM. There is nothing that I can't throw at it that it doesn't handle well. And it didn't cost me much.
Now, there is always better and faster. But I'm very happy with my new rig and so is my wallet

If you have an FX-6300 and are therefore invested in the AM3+ platform, then yes, you're better off sticking with it until the next upgrade.
However, if you're building from scratch, then the AM3+ platform makes no sense at all.

still disagree there
I was coming from a 6600@3.2 and chose the 8370: €180 CPU, €140 MB, €70 rad, and €90 for 32GB DDR3.
The Intel way would have costed more, and would have been too much for what I'm doing. Meaning I play *old* games (GW 1&2, TF2, RO, X-Com2...), lots of browsing, video transcoding (mkv-->mp4), ... Nothing high level. This CPU gives me more than I can ask and I'm really happy with it

You just keep repeating how you are happy with it.... It's a dead platform. Investing in AM3+ makes 0 sense whenever you are creating a build FROM SCRATCH. Leaves no room for major upgrades, there's no real benefit except price. And you could invest in a OLDER i5 4460 that is the SAME PRICE as an 8370 and still outperforms.
