Looking to upgrade CPU

yes, the FX8350 is the best cheapest Am3+ CPU you can get (30W more TDP than 4300, more cooling system is good)
OR (not a good choice) AMD FX 9590, the fastest amongst the AM3+ yet, the most power hungry beast among all beast (220W TDP, complete cooling system is required)

what CPU cooler you use? 220W TDP Cooler? (if you don't know what TDP is, TDP is the maximum heat produced by CPU while at its full load, not the power consumption)

I don't think 650W is enough for heavy gaming for 9590, 800 or 850W is what you want for minimum PSU for 9590 (this is a freak power hungry) (or 1000W for safety and headroom)
with 650W, 8350 is what you best bet, or 8370 with ~50$ more

The 9590 takes a crap ton of power, which equals heat.
A lot of lower end motherboards won't run it.
An 8350 can and will OC to close to what a 9590 runs at.

We will need to know the exact motherboard you have, along with other system specs.
Some of the cheap mobo's have an issue going to an 8350, most do not.

Doing this swap only makes sense IF you get the 8350 really cheap, and don't need to spend any extra or very much on extra cooling.

You WILL see an improvement, a friend of mine did this swap when I sent him the parts from my old build.
But the improvement won't be utterly amazing. Mostly noticeable in modern multithreaded games.

If you can do this swap for a total cost of under $100 USD, including a cpu cooler if you need a better one, it's worth considering.
If it costs much more than that, save your money. Add it to the "upgrade my pc" pile.
It's $300 ish USD to go to a Ryzen 3 with B350 mobo and ddr4 ram. ( assuming budget friendly ram)
New gen Ryzen coming in a few months. Which means current gen might get even cheaper.

I suggest those ideas because I do appreciate that at a young age, you can't just whip out the credit card and go nuts on newegg. So having a long hard think on your options and how to spend your cash is a thing.

At under $100 this can make sense. A Hyper 212 or other good budget cooler is more than enough for an 8350, even OC'd to some reasonable level. ( 4.4-4.6, 2400 northbridge.)
The reason the motherboard model is important is because really budget mobos do not have enough VRM (power to cpu socket), for the increased juice an 8350 takes over a 4300.
Also, older boards might need a bios flash to support an 8350.
While not common, it IS possible.
So knowing it will work is kind of important.

From your supplied info, I'd say psu and case cooling are not an issue.
I went from a X2 255, to a 975 BE, to an 8350, so I have some experience with this upgrade path.
Remember the $5 for thermal paste!

CPU-Z will tell you the model of mobo. And other info that's handy to know

might I suggest you take your pc to qualified personnel to get your upgrade done with parts in hand.

1. look at your motherboard and tell us what is the NUMBER on it.
2. you could run a program called SPECCY and tell us what is reported (take a snapshot , upload to imguyr.com and report us the link to the image.
3. bios is what makes the motherboard boot and function before you can launch the operating system of choice on your system
4. usually F2 or DEL key are used to access the Bios, should you .. I have doubts...
5. Thermal past is a thin layer of heat transferring material that helps the heat dissipate from the cpu to the large heatsink, which is normally cooled by a fan drawing air through it. keeping your cpu at a valid temperature instead of burning up and dying.

Going to say Paladin's suggestion at the top of his post should probably be option A here.
Option B is to continue to use your PC as it is, continue to ask questions here, we don't mind answering.
Doing some Youtube research for videos on how to do what you want to will help your pc knowledge, even if you don't actually do this job yourself.
Google is your friend, and there are literally hundreds of Youtube videos on swapping parts out in your PC.

Also a good video to watch.

We get notifications when we visit the site to let us know someone else posted in this thread.
So don't worry about it "dying"

AMD Fx 8350 is a better option if you considering price with temps. You can easily overclock FX 8350 close to FX 9 series CPU but with a good air cooler or liquid whatever you can choose.

Changing platform makes this a $300-$500 job, not a $100 and change one.
Whether you do the swap yourself depends on your level of confidence to do it.
It's not hard, but the first time i did this on my own PC I was scared out of my mind I would ah heck it up!
Having a laptop/tablet handy to watch and replay the best instructional video you find is very handy.

A Hyper 212 or other $30 ish USD cooler is more than enough for the 8350.
A lot of new coolers have universal brackets included, and will fit BOTH your current mobo, and one you buy in the future. So that's another thing to see if you can use the same one now AND later.
Confirming that an 8350 is a drop in swap for you depends on knowing the exact model of mobo.
This is the most important question we need answered to help you decide.

Deciding on which option to go with, ( 8350 swap, or new platform, cpu/mobo/ram/fresh install of Windows)
is a budget decision.
At $100-$125 ish USD total job cost for the 8350 swap, it makes sense.
A platform upgrade, while a great idea for your system, is between 4 and 5 times as much money.
Then of course, you get to participate in the madness that is AMD vs Intel!
Yay for you!!

I'm going to suggest that research, video watching, and learning will be valuable no matter what you do.
So do that first. Take your time here. I/We want you to be comfortable with the idea of cpu replacement/system building before you plunk down your hard earned cash and then have problems afterwards.

This has the added benefit of.
1) Second gen Ryzen coming out.
2) Budget mobos for Intel's new cpu's coming out
3) Ram prices coming down? I hear rumours that ram MAY come down in price.

The above all has the possibility of making things cost less one way or another.
And gives you time to stash a few more dollars in to the "Upgrade my PC" piggybank, increasing your options.

*Note to other posters in this thread.
Can we agree not to start the Intel vs AMD madness just yet? The thread will get derailed and the OP will not get the answers he is actually looking for. If the OP decides he is in a position to spend a bunch of money, then we can get in to it.

Depends on what Intel processor. The FX series rival Intel lineup may not be a bad switch, but if you want the long run, coffee lake intel chips is the way to go.

For the Intel Lineup, affirmative.
