m confused in processor intel i5 3570K or amd bulldozer fx 8350
gpu 7750 1gb or 7850 2gb
and should i get 8 gb ram or 16 gb
m a hardcore gamer wanna play every game atleast in medium setting and dnt wanna update this system for 4-5 years last but not the least is this setup good for high level computer engineering

Go for the I5-3570k and the 7850, which should give you good fps at medium and high
