I am another Gygabye AGP hell person. I even tried two different revisions, cause I found a newer one used real cheap. Didn't like either one of them. The epox has been absolutely great since i got it and put the same hardware on it. Very stable, and sorry, but it was noticable faster too. I didn't benchmark it with sandra or anything, but I run SETI and the gigabyte with the same hardware would do a work unit in a range between 16-20 hrs. The epox does it in 12-14.
Good luck.
