Thanks Hidden for information. It is much appreciated. Actually i was talking about Graphic Card RAM. Just missed the "G". That's what caused the confusion. I have edited my post. In Pakistan mostly we find GDDR3 cards. I don't know why, But we mostly get outdated hardware in Pakistan in most cities.

Here is my system information

Dell Precision T1650
Core i5 3rd Generation 3.6 GHz Processor
4 GB DDR3 Ram

After reading the information you gave me, i found this in my budget NVIDIA Quadro 2000.
