Apologies for another upgrade thread but i'm a bit out of the loop at the moment. I originally built my PC around the end of 2012, without really knowing how much I planned on playing games. At the time I was doing a lot of small freelance editing work thus I went for a decent build. Recently I've started playing a lot of battlefield 4 and various other games and the upgrade itch is getting increasingly stronger
Do I swap out everything, for the more updated equivalent, which I presume will give me a decent increase in gaming quality and everything else? Or do I get an SSD for windows/frequently used applications and upgrade my GPU?
