Will this graphic card speed my pc up?

I have installed a Nvidia GeForce 9800GT 1048, Im thinking of getting a Gainward Geforce GTX 460 GS 2048GB GDDR5 Graphics Card, will this eb better for FSX?
Thanks. Also thinking of upgrading processor from Intel Core 2 Quad Q6600 2.4ghz 1066 fsb, to a Core 2 Quad Q9650 3Ghz 1333fsb,
Will both of these give a lot more performance?
thanks again
