I bought a herc 9800xt and am trying it out on a temporary computer. This computer isn't that great, but I still dont know why my 3dmark score is only 11500 running the video card at 430/380. The specs of this computer are AMD 1800+ (not oced), 40 gig hd, 512 mb of 2100 ram, unknown mobo. This mobo will only let me run at 4x, but i dont think running between 4x and 8x would be THAT great of a difference. Does anyone know whats going on?
