Well, you're not going to get much power with that price range. Maybe 600-800 for a lower end gaming computer, 900-1100 for a medium power and 1200+ for powerful/uber... But look at the specs for whichever game you're trying to play... A newer FPS, will require something that costs at least 1000+ If you like older games, though, you might be able to work in your price range. Try and find outdated graphic/sound cards.
And to save some money on a Computer monitor, just buy an HDMI cord and hook your desktop up to your TV.
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.
