Graphic card confusion!!!

Hi.

i am a digit subscriber. I am looking to buy Forsa 7600GT. Thanks to
your magazine that helped me decide.
i have a pentium D 2.66 dual core processor, intel D101GGC mother
board, 512 mb ddr ram and a regular 15" monitor.
Will this card work on my system, if not then whic card should i buy?
I have a budget of around 8.5k. I hope this card has onboard memory
and does not use any hyper-memory or turbo-cache funda's.
Can i get this card somewhere in pune?
Please advice.

thanks & regards,
Vivek
