I heard it's a bit better. I want to change to windows 8 myself but not just yet.
I mean as long as I don't have a touch screen monitor, it's a "meh". If everything is just working fine, why would I wanna update it?

If the computer you're going to install windows 8 doesn't have a touch-screen then installing it is pointless because it will just consume memory for features a computer can't support.

i agree with all the above ... But i heard W8 is faster ... Just not willing to try it now ..

I'm not really a big fan of W8 because I just dislike the homescreen and the way it works. But this is your call

Windows 8 is pretty simple. Every day I'm working I'm using Windows 8 in some manner. Setting up computers or showing people how to use the basics.
It's OK to have on any machine but I'd strongly argue against putting it on a desktop. Windows 8 is more touch orientated. It works fine on laptops as you have a touchpad. Touchscreens are most ideal. But on desktop machines, the only benefit is the speed. Other than that it's a pain.
I've upgraded one computer from windows vista to windows 8. Surprisingly the laptop worked very well and naturally *insert vista hate which I don't understand myself*
If you're comfortable with what you have, maybe stay put. If you really want to try it you can but I'd back up your things first because if you don't like it, you just wasted however much money and to undo it you need to restore the machine.
With my own windows 8 laptop. I bought it more for the hardware. I have a razer mouse and keyboard plugged into it. I hardly use any windows 8 feature that's on it. Like the multitasking and so forth. I just use it like a typical machine.

And as for you,
You can modify Windows 8 to look more like the old OS. Normal start bar and everything. I've not looked into it myself but I've come across a laptop with it. Think it was "Windows Shell" or something? It looked awful frankly but it's possible all the same.
You can also modify it to start directly into the desktop rather than the start screen.

EDIT: In fact, as people are saying below, there's an update for Windows 8, Windows 8.1, which will allow you to do this without downloading anything from third party sites.

I don't trust windows 8 and windows 7 is still good for me.:) Windows 8 need more updates.>.>

EDIT: Removed a bunch of crap... I was half asleep, sorry about that.

Stick with Windows 7, dude.

Unless, you get rid of that new GUI.

Then Windows 8 is faster.

But I think Windows 7 is better by far right now, and easier.

Also, you might want to wait until the 8.1 update, where they give the option to remove metro.

Besides that, I would wait maybe a year or half a year, until more things become compatible with Windows 8.

(That's what me and my dad does with consoles and new OSes, waits until more stuff is out there, and then gets it.)

Windows 8 is essentially windows 7 but with a different start menu and better performance. I loved it, didn't have any issues and metro was easy to get used to. I got it for free though through my college, i'm not sure it's worth buying when you already have windows 7. If you are planning on buying it, wait a month or two and 8.1 will be out which has windows aero re-integrated and the option to disable metro and turn back to windows 7 style taskbar, which essentially makes it just a much faster windows 7.

I used Windows 7 on my PC before I got my Mac. There's a saying about Windows operating systems. They go good,bad,good,bad. For example.

Windows 95-bad
Windows-98-good
Windows-2000/ME-bad
Windows XP-good
Windows Vista-bad
Windows 7-good
Windows 8-bad

Hmm... I've used Windows 8 on my grandma's computer. You need a little learning to get the hang of it and I haven't got that yet.
It took me about 4 MINUTES to see how to turn it off... xD. Things are lost in real deep. I believe though that it works faster but I just don't like the way it works, if that would be an operation system for a tablet it might be more ok, but PLEASE never put that on pc lol.
I believe there is also alot of hotkeys you can use on it but never found them on the manual.

Also the operating system feels smartphone-ish. Well Nokia Lumia has Windows 8 pretty much.

Just listing my opinions here, if you want to get Windows 8 it's your choise

I'll just wait Windows Blue. Search for it guys.

Windows 8 is terrible! don't touch it!

Windows 7 is the best for now...

1. I don't expect your performance will change much, specially not for the better, it came out way too fast after windows 7 to have any major performance breakthroughs. Will proly just eat a bit more ram depending on what settings you use and that's about it.
2. You can always bet on compatibility issues with older apps when upgrading your operating system. Now wether it's gonna be a game you really don't give a ******* about or your most beloved oldie that really depends on your luck.;)
3. Can't speak about advantages/disatvantages or cool features since I never installed it, all I know is from what I've seen metro bites the big one, and doesn't seem oriented towards us core gamers.
4. Worth buying? I wouldn't even bother to pirate that thing!

Windows 8 is exactly the same architecture as windows 7, it is essentially the same operating system but they have optimised the RAM usage so it runs on about 50% less RAM than windows 7, also improvements on CPU usage. Being that it's the same architecture as windows 7, pretty much every application works perfectly fine but might not be able to utilise the better RAM system until the vendor updates the software.
Windows 8 is essentially windows 7 with better performance and a new GUI

I have Windo 8 on my desktop at home and i love it. Its confussing at first but then its easy to get use too. I would recamond it. I only had one problem is it once took forever to shut down and i had to restart the whole window system and lost everything. But beside that its works fine

I absolutely love Win8. It's fast and pretty. I definitely think it is an improvement over Win7, however I don't think it'll adversely or positively affect your gaming experience.

It does not when you have a fast PC , but my toaster said otherwise.
(PS. Its not caused because I did a clean install and such btw)

Well Windows 8 in useful in Ipads. Touch screen on bigger windows: easier than little ones (geniouss )

On the computer I use windows 7 because its fast for me and much easier for me to handle. my dads laptop was built with windows 8, it seems to look really good but there's a lot of different things on it to where I have no idea what goes where...it takes a little bit to get use to like Naikey said above, but to me, I think I'm going to stick with windows 7
