How good is the 8600gt?

Hi everyone i want to know really how good is the Zogis 8600gt , im asking because is the better card i found for an affordable price. I really want to play games like World in Conflict or the upcoming Starcraft II.

So is this card enough? Or should i save money for a better one?...

Thanks in advance

Well i saw this 3850 and is about $100 more but i guess i can save that much..

Anyways how good is it for actual games or the games i mentionated before?
