You would be MUCH better off getting the 1gb gtx560 or amd 6850/6870 cards. (video ram has very little to do with performance). Well really no game uses more then 1gb of ram, unless played at very high resolutions (above 1080P) or you are using multi monitors.
Like at when gaming @ 1920x1080 1gb gtx550 vs 2gb gtx550, id say the difference would only be 1-2 fps, and the higher the resolution, the more increase you would see, but still not anything to go omg over, like at 2650x1600 it would probably be only like 5 or so fps more, if using 3 monitors in surround for 5670x1080 it when vram makes quite a bit of difference. Thats only when comparing EXACT same card, if you get a better card like ones I listed, they would give MUCH better fps then just having a lower card with more vram.
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.
