My computer is starting to lack a bit on videogame performace and fps, with that said, would buying a new graphics card help resolving the issue? my computer is a desktop, i have a geforce GTX 750 graphics card! Now another question that i have is, because i already have the GTX 750 , could i buy a cheaper graphics card and then together with the one i have would it have the same power has just having one 1080 for example, cuz i wanna spend the least money i can xp! Thx
