Hi! I've got a GA-MA78GPM-DS2H, which has an integrated ATI HD3200. According to the docs, it can do "hybrid" crossfire with a "compatible" GPU - I assume a 3000 series of some sort? Has anyone paired this (or a sibling) mb with a HD3870? I'm not sure which HD3000 series cards support hybrid crossfile, but I guess they all do? Just trying to figure out what's the most powerful card I can stick in this system...
