Would you need the other basics as well?? keyboard, mouse, speakers, OS, monitor/LCD, etc... Or are you going to use what you have now? The OS might be the big one if you have a retail machine with it already loaded. If you have the OS disk, then I'll shut up, but...
I am not the one to suggest what part you should or should not get, this video card or that... This size hard drive or that one, etc... Just something to consider if you need to get the basics.
