the b3 series, dont really run much hotter if at all, and they still overclock great. but the way ppl look at it is why buy a old revision? its hard to sell cpu's like that, i thought 250 might be too high and think maybe 200 be good, but just see if u get any offers at 250, there are some dumb ppl on ebay. some of the people here sell their item second hand for more then they paid for em new. xD
