Windows 10: Windows 10 appears to have made all my games get less performance...

Hello, I will try to make this as short as I can. I was using windows 7 and playing all my games decent, never had a game I bought a game I couldnt play with some settings tweaks. (I play minecraft and games like that but my pc is good enough to run better games like far cry 4). I am also a streamer and a very small one at that and never had issues doing so. However when I saw the chance to grab windows 10 everything went downhill. At first I was just having little errors so I factory reset to a clean windows 10. I then got all my important files like virus protectors and drivers, etc. This didnt seem to help whatsoever. Every game (im not exaggerating) that I play is seeing a FPS loss and performance loss in some way even if only 5FPS. This, as you could imagine, is a problem. I cant stream either because then the performance gets even worse making my games unplayable. None of my 10 other friends who have upgraded have any issues and im the lone wolf here. It cant really be much else I can think of because I wiped my PC with the factory windows 10. Heres my specs that I know if it helps.
CPU- i5-2500k 4 core 3.30Ghz
Ram-8GB
GPU-550ti
Hardrive-1 terra
Any help is appreciated considering until its fixed I cant stream and I also cant play my games with full enjoyment.

How about games? Windows 10

Hey, I was wondering about if the windows 10 will be good enough to play old and new games, Just like the Windows 7 is today? Not sure I dare to upgrade to windows 10 if it can't handle the games I play today.

I also wondering about how much the windows 10 will require from the computer. I know Vista took alot from the computer so it was hard to ever play a game with good grafic since the operative system took that much. Will Windows 10 take less? So my computer
wont perform worse after my installation to windows 10?

I got the windows 7 Atm and it works fine to all the games I play. but will it be worth to get windows 10 for gaming?..

 

Upgrade to Windows 10

I upgraded to Windows 10 as soon as it offered to me in August, and I then hoped that with the OS constant updates they could improve its performance, but so far it's only getting worse: slower, less efficient,
less reliable and, worst of all, Google Chrome is always crashing, not to mention problems with Yahoo and even Microsoft apps such as Word and Power Point. Now, is Windows 10 really less reliable
than Windows 7 --I mean, for folks who don't use it for games or just for fun? is it worth returning to Windows 7?
