Your onboard AGP graphics might even be faster than the PCI 5200! Don't waste your money on a PCI graphics card. Better to upgrade the mainboard to something decent with an AGP slot, it's no big deal. Just rip it all apart and start again!

Any Newbies or anyone planning a purchase reading this...... don't buy a system with onboard graphics..... not if you want to have decent graphics.
Do you mean like the Pic of my X-15? It's the signature in my account settings in these forums. Or if you mean actually posting a pic, look at the instructions in the screenshot forums.
You may improve your onboard graphics, (I assume thats what you have) by going into your BIOS settings at bootup, and allocate as much shared ram as possible to the onboard graphics chip. The RAM will be "robbed" from your main memory and not "shared" as implied. So you need sufficient RAM to do that.
ie. If you have 512mb RAM
Share 128mb (many boards only share up to 32 or64mb)
Windows uses 120mb
Flight sim uses 120mb........
see the ram dwindling away?
Don't confuse the shared ram setting with the graphics window or graphics aperature setting. They are different.
