Nvidia PCI-E Cards.

Hi. I was just wondering... Out of all these cards, which should i choose.
Basically, my situation is that.. i have a EVGA 680i 122 mobo and i'm probably going to do SLI, maybe even 3-way but i'm probably going to gradually build up to 3 PCI-E cards. For the computer i have right now. I have a NVidia Quadro FX 1500. I'm not sure where this stands on the list, since it's not (or i don't think it is) SLI verified. BTW, could someone tell me, if it were to be on the list. How good is the QUadro FX 1500 compared to these video cards anyways? But my main point is.. i'm going to buy ONE of these for starters, then i will build up to 2 in probably about.. 3-4 months, then by another one for 3-way (if it's still of benefit by that time), in another 2-3 months after that. And... i just want to know (for a somewhat cheap price.. probably about below $225 each card) which one of these is the way i should take... It seems like everyone likes the 8800 GT, because it's cheap for its price, but it can't go 3-Way. SO..out of the rest.. which is best?

I have read the SLi/Crossfire FAQ's post... and it DID help a lot, but there is still some confusion as to which card is better. I'm assuming as you go up the ladder... it video cards and performance gets better.. but which one is like actually the best for it's price? It's like comparing a Q6600 and E8400. They're both pretty equal, even though E8400 is a lower level and Q6600 is higher... People seem to like them both a lot because of their OC abilities.
