I used to hear one person rave about the X850 being great for gaming. Currently I just dropped an MSI Radeon model X1300 Pro 256mb card in at the same time a board was replaced to save on overall costs on the older case here. The 6800 models are roughy the equivalent for the older Radeon X700-X850 models if you intend on NVidia there. So far the X1300 Pro for just under $80- at one vendor has met expectation there. When Half Life 2 gets reinstalled since the board was recently swapped out I can let you know how the current PCI-E card performs compared to the AGP model now in limbo.
