Is it worth it?

So I need a little help here.....
With respect to the video display card:
The one I have:http://www.newegg.com/Product/Product.aspx?Item=N82E16814150330
I have two days to get this card in the mail for an RMA because it's a little screwy.
The one I am thinking about: http://www.newegg.com/Product/Product.a ... 6814130442
Compairing the specs side by side I am bitten with the "more is better" bug. With FSX...is it worth the 100 bucks more?
Thanks
