People says HD4850 is great card, but I'm interested in FSX and now the 9800GTX+ was released.Could you tell how the 9800GTX performs in FSX ?Thanks,Ulisses

Anything beyond the 8800GT isn't going to help FS. The 9800s will work just fine. If it's just FSX, save your dough. But if you want to play Crysis, that GTX260 is touching $250 at Newegg these days. Dat's a dawg that'll hunt.

I have a 9800GTX, runs fine for me, in FSX, COD4, etc. Love it.
