I'm deciding between the RADEON X850 PRO or RADEON X800 XL . My computer uses only AGP. I'm looking for a midrange card that is below 200 dollars. Also when looking at the specs I was told to pay attention to the parallel rendering pipelines then the core clock and memory clock. I'm not too sure whats more important. Also, if none of the cards i have mentioned above are no good should i just go with the X1300/X1600 models from ati?
