So I have just updated from intel pentium g3258 to intel i5 4790k. I have kept the same other components which were h81m-e mobo, 8gb ram, 430w corsair psu. It all runs fine just runs at the same speed as my old cpu which i'm pretty sure it shouldn't. I don't know what to do to make it quicker and running games such as Ark and GTA, lagg on minimal settings and reviews of the i5 said it can play basically every game on medium graphics. Do i have to do something after putting my new CPU in or does it work straight away?
