get a 7950gt and convert it to a fx 3500, a much better option for 3d than the quadro fx 1500 and the 8800gts640mb, not the quadro 1500 because of price to performance and not eh 8800gts640 because it isn't designed for that kinda thing...
adobe photoshop cs3? i swear that thing is more cpu intensive than anything...

i actually meant that i'm NOT useing 3D softwere and rendering,
only Avid and CS3, that's the reason i wanted to know the difference between the cards.
and if i don't need FX card, should i get the 8800GTS or a cheaper card?
Well, if you're using photoshop then it doesn't really make a difference. Personally I'd just stick with whatever GPU you already have and then just get a powerful CPU. Quadros are more for 3D rendering like Maya or Softimage.
