I recently just put a new gpu and motherboard evereything was working fine but I had a few issues. I took it to the shop and they fixed it. when I tried to run any online games my fps would be horrible but offline it would be fantastic. I am using the same connection/router I used before, before I was having no issues but since I got it back online games are unplayable my gpu is a gtx 780 and my cpu is a i7 2600k.
