I run Linux Mint (MATE), started at 17.3 now running 19. Here's why I use it
 
1) Great for breathing new life into old machines. It means I can buy cheap refurb laptops, install Linux, and away we go. It's saved me a lot of money because I need to upgrade less often. One of my laptops ran for 10 years, four of those on Linux after it just couldn't run Windows 7 any more without freezing up and crashing all the time (Lenovo T500 2009-2019, RIP). I also imagine it's better for the environment that way as you get a longer usable life out of your computer.
 
2) Free.
 
3) Gets you away from Windows' data mining. So I find it's nice for the privacy oriented.
 
4) Unless you're into gaming or specific use applications (video editing, photo editing, etc), I find it's really all you need. If you're something looking to browse the web, watch netflix and youtube, and do some word processing and officey kind of stuff, then you need look no further. So I think a significant number of users could switch to Linux and not be left wanting.
 
5) Non-intrusive updates. I can download and install system updates without needing to pause what I'm doing or restart the machine.
 
6) There's a distro for everyone and you can try them out risk free. I settled on Mint because I was coming from Windows and it felt very familiar and it's ready out-of-the-box.
 
7) Doesn't seem to slow down over time the way Windows seemed to.
 
8) It actually detects external harddrives and USB sticks when inserted on the first try. Windows seems very flakey by comparison.
 
9) Tonnes of useful free packages. I've downloaded some very useful PDF tools for merging and cutting up PDFs and it's been a huge help compared to Windows where you either have to buy software or put your faith in some really dodgy free software.

I do want to clarify, though, that I don't think Linux is for everyone. If you need to edit video, depend on third party peripherals, or have some other use case that relies on software or hardware that needs tinkering to get working on Linux, then it's probably not for you as Windows or MacOS would likely be just more convenient than tinkering or setting up a VM. But, I think a significant number of people use their computers for basic stuff like web browsing, media consumption (netflix, youtube, etc), and basic office productivity and those users could use a distro like Mint and never look back.

 I never thought an OS could get me excited. Linus Mint changed that.
 
 

Oh ho, you're approaching me?
 
First of all, Linux is the BEST OS ever thanks to being open source and completely open to customization. If you're a giganerd and want to change something, you are absolutely free to do so and make it your own as many other nerds have done to create their own distros.
 
EVERYTHING IS FREE. There are certain paid services, but if I want to run a program on Linux, I can find a comparable piece of open source software that works just as well if not better than a paid version for Windows or Mac.
 
THE UTILITIES. I use drive cloning on Puppy more than almost any other utility and it is far more convenient than trying to do a Windows or Mac variation of this. As an actual IT person in an office, Linux is my default OS on my laptop so when I don't need Active Directory for something, I can just use Linux.
 
I can run Linux on basically anything and revive old hardware with it. No longer do I need to toss out old tech when I can just run Linux on it and keep using my machines while not contributing to e-waste. 
 
Gaming on Linux has come a long way in the past few years. While not all of my favorite titles are compatible yet, developers are making Linux versions of games and developers are patching things so I can play all my games without needing Windows spying on me.
 
The community surrounding it. Windows is just what the masses use, Mac still carries a yuppie air of superiority about it, but Linux? You see another distro user and you're both instantly friends as you bond over your love of the kernel.
 
 
It reminds me of Anthony and anything involving Anthony is a good thing.

The thing is that Windows has only one interface.  The various Linux distros have so many different interfaces and menus that it's always easier to say "enter this command in the terminal" than to ask what distro and desktop environment someone uses and to then tell them which buttons to look for and which options to click in which menus.  I don't like using command line either, but it often is just a lot more convenient than using the UI. 
 
I'd reply to the "Linux forums vs Microsoft support" comment, but in all fairness the last time I contacted Microsoft's support was because of problems with the then newly released Vista SP1.  Their support was pretty horrible back then.  Judging by the irrelevant and generic "solutions" that their reps post in the answers.microsoft.com community forum whenever someone reports a problem, I doubt that there has been any improvement since.

Been running Mint on my laptop (Samsung NP900X4D) for several years now.  
 
I had to install no drivers at all, even most of the function keys (screen brightness, keyboard backlight brightness, volume, touchpad on/off) worked out of the box. 
Only the manual fan on/off and the WiFi on/off button don't do anything, but I suspect that this functionality under Windows is part of Samsung's own software suite.  It shouldn't be that hard to enable it under Linux too, but I don't ever use those buttons so I haven't bothered to look into it. 
 
Why I prefer it:
the responsiveness.  Everything is smoother and faster, even the mouse and trackpad response feels much better than on Windows (different accelleration?). no forced updates, no built-in advertisements, no unnecessary telemetry.  updates won't add or remove programs or adjust your privacy settings, unlike some other OS does on a regular basis. using repositories means that all your installed programs are automatically updated with a single command, no more need to let the programs themselves check for updates or to download them individually. you can keep using your programs while the system is updating them.  Also no need to stop working or immediately restart when there is an OS update.  the ability to boot from an external USB3 drive.  I find that having several (encrypted) external drives and using those is much more convenient than setting up a multiboot environment.  This allows me to do any financial and crypto stuff on a completely separate OS without actually having to buy a different machine for that purpose.  Even if there would be something nasty on my regular install, there's just no way for it to jump over.  choice.  Don't like something?  Change it.  Switch to a completely different distro if you want, there's plenty of stuff out there to suit everyone's tastes.  As long as you have a separate home partition set up, you don't even need to move or back up your files (although the latter is still always a good idea) free ... as in "freedom" as well as "free beer".   Security issues get patched a LOT faster.   
In fairness I have to add that I usually run Windows 7 on my main PC, but I will completely switch that one over to Linux when 7 goes EoL. 
 
Apart from GTA5, which I haven't played in months anyway, my entire Steam library has native Linux support. 
I do have this desire to pick up WoW Classic to relive my youth, but not if that means having to install Windows 8.1 or 10 in a couple of months. 

The following I really like about Linux, no particular order:
Linux distros (with the exception of Suse Linux Enterprise and RedHat) are free of charge No data collection/ telemetry (telemetry option is available in Ubuntu but can be disabled) Stability Faster, more reliable update process (no "Updating Windows 30% done. Do not turn off the Computer", just a simple and quick reboot at best) Tons of free and open source software through the repositories (e.g. for development but also for basically every other task you can imagine) Customizability No bloatware (Candy Crush and alike) Performance on both old and new hardware (due to the large number of different distros, nearly every system, even quite aged ones, can still be used in a useful and productive way) Possibility to run Linux on embedded and low power systems Security: Even when logged in to the system as root, you usually have to enter your password before applications can perform certain critical tasks. Thus it is harder for malware to run with elevated privileges

One of my jobs is to deploy Alcatel PBXs, which use a very cut down version of Linux as their OS. What I like about that, is the performance! 256MB of RAM and it just runs like butter!

Works better on old/weak hardware.
IMO sexier (Deepin OwO)
More secure in terms of viruses
FREE!
Easy to install (except Arch lol)
Customizable (KDE especially)
Easy to install software (espcially on Arch-based stuff with the AUR and whatnot)
Less spying/data collection (none on some distros)
More variety (distro for everything from a NAS to tablets to just regular desktops)

Thanks @OppositeCube yeah used parts especially evga and zotac gpu's (5 year warranty) are great deals due to the warranty left,its like buying a new gpu for half price. 

wow. That is the Perfect Build! @jsonschema Just Go with this if you are Into new Parts!.
If you are Into the used Market you can get a Gtx 1070 or a 980ti for $200 at ebay.
They are very Good for 1080p 144fps gaming in sports titles like Overwatch.
But RX580 is good too for many Games at 1080 144ps like Csgo but It can also run games at 1440p 60fps!. In almost every Game. In non- competitive like Grand Theft Auto 5 (GTA 5) I would go for 1440p. 
Edit: Hm. The case in this list does not have a Front panel.
You have like $20 dollars left and if you just spend $10 more You can get a Good sexier a white NZXT H500 for $67
https://www.amazon.com/dp/B07C3SQP9V/ref=twister_B07F4G24W3?_encoding=UTF8&th=1
In total $665.
For $15 more you can get a sexier look.
 
 

But it is Good and respectable it is Better than the SD 660 (or 636) Found is latest Xioami Redimi series.

Well me too I don't care about it too. since also in my country no one uses it. The other person @TheNuzziNuzz was saying something about it  

I edited my post. Go check it again.
iOS 11 was buggy as hell. I had clash of clan suddenly turning off sound. I had back button disappear on me in settings app. I had wifi giving me not connected error even though signal is full strength and connected. It was only couple months into an update did these disappear. For a $1k phone, I expect my user experience to be perfect.
 
Oh, my biggest grip, it can't fcking transfer or store files from my Linux computers. 
 

As a former iPhone x user I can tell you my user experience has proven you wrong. 
 
Doesn't matter if apple sells more than top 5 Android oem. Android is an OS, not a prudct made by just one company. It is collective that counts. Who cares if apple sells more Macs than Dell Windows pc for example? Windows still outrank Mac in unit sales.
 
Google play store has many apps iOS doesn't. E.g. file manager. Torrent downloader. Nientedo D's, nes emulators, linux deploy, droiddrive, SUPERSU(will app store ever have cydia? Lol). It can do many things like turning your phone into network repeater(netshare). Firefox can't install extension due to iOS limitation. On Android it can.
 
iOS has none of such capability. It's softwares ain't crap but they just can't do so many things Android can.

The 1070 is a much stronger card than the 580. So all things being equal that would be my choice. Just make sure you have the opportunity to test the card if buying second hand.
 
As to the statement on overclocking. I have seen 15-20 fps in games/benchmarks from just an overclock. Now this is very dependent on the gpu, game, etc. If for instance you buy a stock clock and boost 1070 that means it will boost to only 1683mhz and the memory will be at 8008mhz. Now when you start buying factory OC cards that changes things, but you average 1070 can normally overclock to around 2000-2050 mhz in most cases (some a bit higher). Then there is the fact you can normally get the memory on these to 10ghz even on a bad overclocking cards 9ghz should be possible.
 
So just going from 1683 to 2050 is a 21% performance increase. Then you can get another 2-5% off the memory. So if you purchased a stock clocked card you could see 20-26% increases in FPS.

Ok, I was browsing that on mobile and site isn't exactly mobile friendly.

go with 8gb you can get a used one for max $240
