Get a 7870 ghz, the 660ti is a pos, don't buy it. Get a 4670k, I see no reason in getting z87 if you can't oc your CPU. There are also a lot of parts you haven't listed, so make sure you have them.
Get 8gb ram.
Those components are pretty good, but I would get an i7 processor that can clock at least 3.0 GHz if I were you. The i7 quad cores are much better and more powerful than the i5.
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.
