I would suggest the AMD Radeon HD 6770: http://www.newegg.com/Product/Product.as... You basically shouldn't go for anything below a 6770 if you intend to play high demanding games such as Battlefield 3, Crysis, etc. Spend an extra $30 and you won't regret it. A 6770 will run at probably Med-High settings without lag (depending on your build).
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.
