Wanted to upgrade my graphics card,

within a month or so, and I was thinking of this: http://www.newegg.com/Product/Product.aspx?Item=N82E16814150306

(I have a 8600GT)

Yay? Nay? anything better for under 200?

While I'm here, here are the rest of my specs, should I upgrade anything? (scroll to bottom)
