Building a Computer... - Graphics Cards?

Well I am building a computer... for my first time ever and I am making a shopping list of things I will be buying that are generally within my budget. I am trying to make the computer for gaming, mainly for flight simulators. Anyhow, I have chosen mostly everything as best I can tell, but I know nothing about Graphics Cards. What would be a good semi-high end graphics card to buy? Preferable nVidia but if I have to something else will do. Also I could use some opinions on the parts I have chosen, list below.
Thanks,
Dukes
