PC specs needed to run ultra-high settings??

Hi everyone - for those of you who are able to run NBA 2K9 for PC on ultra-high settings, could you please post your specs? I'm currently running the game on high and don't have ultra-high options. It would really give me a good idea of what part(s) I need to upgrade.

Thanks in advance.

PS - I realize my sound card is really old, but I'm thinking I would need to upgrade more than just that to get things up to ultra-high settings. Should I move to Vista?

You should be running on max judging by your specs. Only the player detail has an ultra high option, I'm guessing you can just force it to "3" in the config.cfg file.
