I have an older computer running windows XP that currently has a Radeon 9250 graphics card, but i found an MSI 5200 card in my basement. Which chip is better? Should i switch to the MSI 5200 or keep the 9250? This computer is mainly used for surfing the internet, email, Microsoft Word, and occasional gaming, but i have another computer i use for most of my games. If someone could help me decide it would be greatly appreciated.
