from what i've read, manufacters other than ati get poorer overclocking results but have better features. i've always bought bba, but that backfired this time with my x800 pro as i wasn't able to mod it to xt. other cards not bba were able to be modded because those manufacters cared more for simple production rather than hindering modding, so they made one pcb for xt's and pro's alike and simply disabled pipelines 13-16. from all i've heard, bba cards cannot be modded from x800 pro to xt. but they overclock well for what they are.
