I am a complete blank canvas when it comes to gaming pc's so please bear with me. I have recently inherited a mid range gaming PC off of a good friend. At present it runs Shogun 2 at a reasonable pace and also crisis 1 is playable. The thing is I want to play games on high settings at least 30 fps and I want to play crisis 3 in particular. So I am looking to upgrade certain components on my Pc but am stuck for which ones. So the question is what components should i upgrade? and what components would be worth keeping?
Any advice would be grateful
