Hello , I have a emachine 1852g , I recently moved all internal parts to a mid tower , and installed a nivida gtx 630 graphics card . It works fine except I can't tell any differience in performance with new card . Can I upgrade the mobo and cpu to improve performance , i'm trying to use rocksmith 2014 with this machine but it seems too weak to run it without freezing up . Any advice would be greatly appreciated , my first attempt to improve my pc on my own and on a budget , thanks.
