Hi Brian, unfortunatly for you I dont think that investing in a new video card is worth it... Your brother's board is pretty old and from my opinion it's the board that is the problem! ATI's 9200 isnt the best card to do 3D, in fact its a super budget video card that was suposed to offer good performances with a low initial cost and yes, it is slow no matter what AGP timings you run it! But your main problem is something called a "bottle neck" caused by the board... Your board cant push data to the other components fast enough to deliver a good performance! My best advice would be to upgrade the system entirely with something that has a little more punch but still in the budget category... But remember one thing, when your buying a motherboard dont go too far in the budget category because its the main thing that causes the system to lag! get a good board with a decent (but budgeted) CPU and some good (but still budget size) memory. for a good budget video card I would recommand that you go with nVidia instead of ATI... More bang for the buck! And if you want to follow my advice with an upgrade then I recommand ASUS for the board and something like a budget oriented OCZ memory kit. Hope this helps a little
