here's an idea, and so far it nvidia is sticking to their naming convention.
every generation, the higher the model number the faster the card is.
let's use your card as an example. gt210 belongs to the 200 series/family.
you have gtx 280, 270, 260. these 3 cards are good, and fast. you have gt210... that is like the lowest among them.
get a decent card please, you have a good cpu
Thanks, this is indeed a solution. I had asked the local dealer here for 7850 model, he quoted me 20K Indian rupees. That's certainly I wasn't looking here. But thanks Cons, I guess it would be only few thousands more I have to spend to upgrade my card from the same 200 family.
