So 2-3 years ago I built my first computer on a $400 budget a amd a8 6600k with a gt 610 for games mainly for league of legends but a year later I went into counter strike global offensive and I love the game practiced it every day with my friends and people I have met and I wanted to upgrade because I was barely squeezing 60fps on 4:3 1024 resolution so I went to upgrade to my brothers cpu a i5-4690k with a really bad video card worse than mine and he got around 80 to 100 fps on 1920 when I went to upgrade I got the same on my old cpu and mother board a A88x-pro to a i5-4690k cpu and z97 anniversary I booted it up downloaded my drivers and deleted my amd went on to csgo on 1920 barely squeezing 30fps at first I was confused but then I asked my brother what I did he said did you fully wipe your computer and reinstall windows 7 and I was like no so I did that wiped out my drivers and went on it again the same result I was mad now but once again I asked my brother and he did his magic with it and updated the bios and got to a point were there was nothing on my computer expect for csgo and google chrome once again 30fps sometimes 50 I don't know what to do now im thinking of returning it and saving to get something else but I was going keep this for a gaming pc till I get a brand new one and have this on has a streaming pc but I don't know what I did wrong.
