So i replaced everything from a Duo-core 2.6 MHz and a video card GeForce 520 to the parts above and still i cant do anything that i was ABLE to before.
Im really only interested in playing league of legends but when i do i get INSANELY low Fps. On my old set up i was running League on middle graphics and was getting around 60 Fps with the only fps drops happening in big fights. Now with the new better set up im trying to run league on Very low settings and getting at most like 45 Fps but usually around 30-35. I have no idea what to really do and honestly ive just been very sad. Ive replaced a ton of stuff to try and figure out the problem and still nothing helps. I have a 600 Watt powersupply which i purchased today and it didnt help anything aswell. I hope someone can help me with this cause i cant stand for this much longer. Thanks
