Specs:

Windows XP Pro SP3

RAM: 2GB DDR 2
Graphics: Asus Radeon EAH3650 256MB PCI-E

I made my computer with this config. Can I play GTA 4 with this config. I am really afraid?

Well yes, you can play but not properly. You will need to go with a minimum settings and fps will not take off.

OK I will change the graphics card very soon. What do you say about Sapphire ATI EAH4670 1GB DDR3

It gives a good performance/price. But be careful, do not take 1 GB. HD 4670 is not powerful enough to take advantage of 1GB of RAM. It has a marketing argument. Take 512 MB instead. With an HD 4670, GTA 4 will run properly, but with a lot of concessions in terms of graphics options.

If you want more powerful then just go for HD 4830. This one will bring you additional comfort.
