Buy that card if you wish, as I keep saying, something like a 6600GT is the card you should be looking at!
To give you an example, a plain Geforce 6600 will out-perform an X600Xt , the GT Variant is quicker again.
Your money, but, why buy the X600Xt when a PCI-e 6600 costs more or less the same and is significantly faster ? - The 6200 will better an X600 ! and there regarded as poor gaming cards !
Your pc is a reasonably good spec, they cut corners, and cost, by fitting basic graphics, by "upgrading" to a low end card, your still missing out on your PC's potential.
Have a look at these benchmarks, ok, they use Doom 3 as a test,instead of FS9, but, you will get a good general idea as to how well a particular card will perform.
