Question i7-9700k

100-150 dollars is probably fair for a used one if you already have a known working board that will accept 8th and 9th Gen Coffee lake and Coffee lake refresh CPUs, and some suitable DDR4 memory.

If you don't, then any amount probably is a bad purchase because honestly it's money much better spent towards a newer platform when you can get into something that really outperforms that CPU for not that much money, now.

I mean, even a current Gen Intel i3-13100 has better multicore performance and MUCH better single core performance, which if this is for gaming is still pretty important. I mean, it's not even close in single core and we're talking a lowly i3 with 4/4.



So you can get into something half decent for pretty cheap, and if you wanted to spend a little more on a 13th Gen i5, the margin goes way up quickly.

300 bucks and you're into a system with FAR better performance than anything you'll get out of a 9700k.

60 bucks more, and assuming you have a graphics card, you're into a whole new world of performance by comparison.

Thanks for the reply, its mainly because I've been wanting to upgrade my cpu and my motherboard (Z370M) only handles up to a i9-9900k so ive decided to go with the i7-9700k
 
So, there's only like a ten percent improvement in single core performance between the 8350k and 9700k. Not super great for a 130-150 dollar upgrade, but I've seen people pay more for less improvement in performance. It does offer like a 50% improvement in multithreaded performance however, so in that aspect it might well be worth it if you can find a working one with no problems from a reputable seller for less than 150 bucks. More than that and you would be wiser to simply make the move I listed earlier AND it would cost you even less because you already have the DDR4.

Would it be possible to make the total around 200$?

That is a pretty good deal on the motherboard, I wouldn't even suggest going for anything cheaper with that on the table. Same price I paid for an ASRock Mini-ITX Z690 a few weeks back.

And weirdly the i5-12400F might be the even better choice for only twenty bucks more. 6c/12t like the i7-8700k

i3-12100 and i3-13100 are both 4 core 8 thread parts, not 4c/4t like the old i3 or 6c/6t like the older i5, or the one standout 8c/8t like the 9700 and 9700k.

would it be better to get a ryzen cpu thats better for cheaper with a mobo that supports it? Since my gpu is already amd

You could sneak a Ryzen 5500 and a B550 motherboard under two hundred, but it isn't the best forward looking CPU with only PCIe 3.0 capability and half the cache of a Ryzen 5600.

If you do a Ryzen 5600 you are looking at 233 dollars or so and Intel starts to look better again

would it be worth trying to find a used cpu ex, I see on ebay a new i3-13100F is going for 100$ or just buy brand new?

Ok, so you are in Brazil? Makes it kind of tough doesn't it, because I know hardware is expensive and hard to come by there for the majority of people.

Obviously that is going to affect purchasing decisions since prices for just about anything you'd care to name are not going to be even remotely similar as the prices in the US and other "western" countries. I think you'll need to see what's actually available to you, or if you don't mind paying all the fees involved with ordering from Amazon, then just weigh your options based on cost vs performance. Or, you of course always have the option of saying "to heck with it" and just buying the best parts you can afford, if you can afford to. It's totally up to you and what you can actually get your hands on and then what you can actually afford.

Have you looked into what you can actually GET a 9700k for, in your country, with all costs factored in? Because it's going to be completely different than, say, for me, in the US. Totally different pricing and fees and taxes, etc. Also probably totally different availability, since many sellers won't ship to some countries or even any countries outside their own.

I'm not in brazil but I lived there for a bit and bought the case there and now I'm back in the US
 
Ah, ok. I see.

Well, I'll tell you what. When it comes to graphics cards and motherboards, I tend to advise people to avoid buying those used for the most part, because those two items are high failure parts overall and there is always a good chance when somebody is selling one used that something is wrong with it. The odds are much better of getting a good part if you're buying a CPU or memory used. Storage devices should never be purchased used. Certainly anything you buy used MIGHT either not work or have a problem, so I generally say if you're going to invest in a new platform, always buy all new parts if for no other reason than the fact that you get a full warranty.

If you're buying replacement or upgrade parts for an older platform, that's when it makes a bit more sense to look at buying used parts but you need to be VERY careful that you are buying from a seller with an exemplary positive feedback rating and a high number of previous sales.

As far as your case is concerned, I was just looking to verify that it would take an ATX motherboard since you currently had a micro ATX board in there. It does, so you should be fine with whatever you decide to do as it will handle ATX, micro ATX, mini ITX, etc.

Yeah I was going to try to find a used cpu, for ex on ebay actually brand new i3-13100F's are going for 100$ and i5-12400F is going for around 120-130
