My specs are:

CPU - intel core 2 duo e4300 1.8ghz
2GB of RAM (DDR2)
Windows 7 64 bit
Current GPU Radeon x1650 256 mb
PSU 400W
Resolution 1440x900
 
What is the budget and why the upgrade?
Also please check the motherboard supports PCI-E cards, it should but you rig is close to the changeover years when PCs switched from AGP to PCI-E graphics slots.
Don't expect stellar performance in current games, even with a stronger card the CPU is going to hold the system back significantly.
