If you went out and put a $500 graphics card in a 10 year old $300 PC.. then yes, things would still look terrible.
If the rest of your system is pretty good and it's being held back by your graphics card, then a new card would improve things. Can you post the rest of your current system specs? Processor? how much Ram do you have?
We would need more information to give you a good answer.
