Yeah, the 3000 is only in the K series chips I believe which actually makes no sense. The K series are the chips that can OC and to OC you need a P67 motherboard which cannot use the integrated video. The H67 boards can use it but they cannot OC. I dunno what Intel was thinking there.
thanks man for tell me difference between p67 or h67 mobs
so i go for p67+i5 2500k along with nvidia gtx460/ati 5770
