The 7870 is a much better graphics card than the 660 since it's not even the Ti version. The FX-6300 will be good enough and you can bump it up later since AMD's gonna release their next CPU line on AM3+ next year. I'd probably go for that.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
