Should I install 64-bit or 32-bit Windows 7?

You haven't mentioned your motherboard. As long as your motherboard has a PCI-E x16 slot,the card will work without any issues. But as a Computer expert,I am seeing two inconsistencies with your system.

1)For systems having 4GB and above,you should install 64Bit operating system. Please note that a 32bit o. S won't detect more than 3GB RAM.So,1GB RAM will be totally waste.

2)Geforce G210 or the card you mentioned is pretty weak and quite outdated. Considering a HD6570 or GT630 or even GT620 will be better if you need basic computing like watching HD films and playing games at low resolution(1024 x 768 and less) at low settings.

I wouldn't imagine that you couldn't as long as you have the correct bus.

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.
