Can you help me to choose the best graphics cards?

Hello everyone,

I have trouble with my present 3-year used graphics card, andI think it's definitely time for a new great graphics card.

I¡¯m wondering if you would like to advise me a good solution that could compatible for my computer system?

2.01GHz
2GB of RAM
AMD Sempron Processor 3400+
ACPI Uniprocessor Computer

I¡¯m having the motherboard sound, as a result, a brand new sound card may also be a good idea.

I'd be very thankful for any advice you can give me.
