Yea the 6200 is a pretty good card, for light to mid gaming. Btw what video card are you buying soon? did you check on the 9400gt yet?
And btw i am going computer shopping soon, and i will be replacing this amd emachine single core with a brand new dual core rig, and i plan to continue using PCI cards. Going to buy a 8600GT PCI as my next card. I hope everything works out better, if so i will be using pci cards until they officially die. My 8400gs is running games really good, but could run much better.
But until i get the new rig, i plan to buy a new pci card for the moment. or i will ahead and buy a new rig.
