that's kind of like asking which is faster, a snail...or a dead snail
the 9400GT would give you a less aggravating gaming experience, what games do you plan to play?
:lol: That is what I call hitting the nail on the head.
But really, it would be helpful to know the rest of your hardware.
Maybe those GPU's are all about you have the horsepower to run?
Considering the game won't be out till next year I'd wait. If you aren't playing any games or Galaxies now it is a bit silly to spend money on tech that will be old when you actually want to play a game.
Now if you are still playing galaxies the HD4760 would be a good choice
