DDR3 is better than DDR2. What kind of ram you have in your system is entirely irrelevant to the ram on your video card. As long as you have a PCIe x16 slot you should be able to use any PCIe video card(as long as your power supply can handle it.)
If you tell use your budget and your resolution we can tell you what cards you should be looking at.

well my budget is abt $150 and my power supply is 420watts,,so which nvidia or ati
card will easily play gta4 crysis type games on high settings,........

You didn't say your resolution but the best card for around $150 is the HD5770. If your resolution is below 1680x1050 though cards closer to $100 should still be very good.

It should perform very well and will be ok for your 420w PSU. Like almost all decent card it does need a 6 pin PCIE power connector however. Your PSU may or may not have one and if not you will need an adapter as from the pics I don't believe one is included.

As for Nvidia vs ATI which is better depends on what cards you are comparing but in general right now Nvidia's card over $100 are overpriced for their performance compared to their ATI counterparts.
