i want a Quadro series card.pls suggest.(low budget)

i want a Quadro series card.pls suggest.

my system config is as follows-:

2.8 Gz Pentium 4 (H.T) processor(the hot one)
915 GAV Intel orignal motherboard
1.75 GB of DDR400 RAM (1GB+256MB+256MB+256MB)
Segate 250GB+320GB Harddisk
Sony DVD writer.
400 watt Colorsit Power supply.

i am learning Maya and i will be working on VFX(dynamics,particles etc) and Digital Fusion.
so i want to buy a graphic card. i have been told to buy a quadro series graphic card,even if it is a low end quadro card. bcoz even a low end quadro is better for Maya than a gaming card(the Geforce series).i don't exctly know the reason of this.
my budget is Rs5000. and i have heard that a quadro card does come in that price.
so pls tell me the price of quadro series cards.any other info on quadro cards is welcome.
and if there is no quadro for Rs5000 then pls tell what is the starting prices of the quadro cards.

ok people i did some research and looks like the cheapest(and the low-end) quadro would cost 7500/-,don't remember the model no though. so i just want to know should i buy the low end quadro or a mid level geforce series card in the same 7500/- budget.
