No No please dont. whatever interface u have AGP or PciEx, dont buy a 6200.
Dont be fooled with tech words such as turbocache or hyper memory. they dont give better quality or FPS. It just means they are sharing precious memory of your system. Unless u r on a very very tight budget, check out the 6600GT 128mb ddr3. Believe me the extra 128 memory on the 256 card doesnt make much of a difference on current games.
the 6600GT is a pretty formidable chipset and it will run ALL games perfectly.
And its a little futureproof !!
