Well Thank you. I have not yet upgraded anything yet but I am planning to upgrade the psu to xfx core550 to meet my gpu which I m also upgrading to r7 265. You are right I m going to use it for gaming purposes only. Games like Assassin creed unity, blackflag, battlefield4, farcry4, watchdogs, division, gta5, cod the new one and all the new games that are gonna come. I want to play on medium to high settings at 1080p. I want to keep this system for approx. 4 years and then I will throw it out and buy a new one.
