Yes, your motherboard will support. But if you r planning to get a 9800GT then just dont. Instead get a HD 6670 1GB DDR5.
It performs almost equally to 9800GT for a less price and less power consumption.
Yes, but watch your PSU (500 watts is probably fine unless you overuse USB ports and have like 3 seperate hard disks) and actual space on mobo (it might take up 2 slots in width, so there must be room for that; the 2nd PCI slot might become unusable).
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.
