if you have the patience and time to look for proper tweaks windows 8.1 becomes a good os for multitasking, gaming.
it is better then w7 and xp ! but pretty similar to w 8 ! having said that ! android is the number one os on the planet ! take a wild guess where dev will bother inputing money for future game ! yep android !
Android is number 1 mobile OS. Windows is still the #1 desktop OS. Game developers aren't going to abandon the #1 desktop OS....especially considering they can do more on desktop than on mobile.
installed it and did some hdd benchmarks and usb3.0 transfers, and performance is no go so i said screw it, cos i need good transfer rates, so i am reverting to win 7. it also broke some apps for me, so overall, ill stick with win 7 thanks guys
