What sort of budget do you have?
You're much better off getting a GTS250 than 9800GTX; they're almost the same card, except the 250 is slightly better and slightly cheaper.
Also they're called graphics cards, not graphical :P
So two graphical cards, two slot fans,...one network card,....would that be too much to ask?
Not particularly, no, but exactly why are you after two (relatively) weak GPUs instead of one strong one like a GTX280?
I also want to have a strong processor...maybe some thing from AMD 64 bit
Um, every AMD processor nowadays is 64-bit. Could you clarify? :P If you want to go AMD, depending on your budget one of the Phenom II X4 chips would probably be a good idea for you.
RAM-wise, why particularly 1600MHz?
I'm sure some of the fokks around here could put something together for you on Newegg (presuming you're from the USA), I would do it myself but I don't work in dollars
