I currently am planning to upgrade my computer sometime in the futue, and have a spare x1300 and (AGP [meaning i wont be able to use it on the new system]) Radeon 9800 Pro. ATI has a trade up program, and i could score an ATI Radeon x1600pro 512mb PCIE for $150 (by trading in either my 9800pro or my x1300. Is it worth the price? Or should I just sell my two radeon cards and buy a nVIDIA card?
