OK, I guess one to look at is that in plain DX7 to DX8 games. Played straight from install with no fancy FSAA or AF applied, then the GF FX wins the fight.
If, on the other hand, you count FSAA and AF as being indespensible in todays games then the GF FX loses big time.
So I would say that if you just wanted to play
games and not stand around and look at the scenery then, yes the GF FX is the fastest card you can buy (and that maybe by clockspeed only
). Otherwise... who cares
