Windows 8 for PC

Ok so i currently have Win 7 (home premium) and have been debating switching to Win 8. What are the positives and negitives to switching? and i am a heavy gamer so will this effect me majorly? I just wanted your guys' thoughts. 

Windows 8 is slightly better for gaming. They aren't noticeable differences. I'd suggest keeping Windows 7 until you build/buy a new system. It isn't worth the upgrade from Windows 7. When you get a new system, there isn't any reason not to get Windows 8. :)

I'm more asking is there a big enough advantage with gaming that i can tell its running faster or something of the sort?

The difference you will notice would be similar to if you overclocked your CPU 0.5 Ghz or something along those lines, not very much.

Well it happend to me that i had problems with some games, so try to inform urself when the games u play work on win8.
The preformance gonna be simular to windows7. 

Like I said, they aren't noticeable differences.
