That can run on

A PD 2.20GHz

1024 MB of RAM

GeForce 7300GS 256 MB 64 bit (yeah i know it sucks, gonna upgrade soon)

And I want some games to test my system to the max please...

On a side note:

Which is better?

GeForce 8800GT 512 MB 256-bit

OR

HIS HD4850 512 MB 256-bit

Both are close in my budget but since I can buy only one, which one should I?
