Benny, you don't even have the PC yet - why does your sig say "AMD Opteron 148 @ 2.9GHz"? You don't know what the **** you're talking about in just about every post you make.
Let me fill you in on overclocking. Rule numero uno: NOTHING is guaranteed. Your chip could be a dud, not able to oc past 2.4. It could be a monster, 3.0+. You don't fscking know, however, until you get the chip in your rig. There are too many variables. And I'd take a 2.7 dual core over a 2.8 single core 100% of the time. Dual core is the future you n00b. GTFO of here. You talk like you own the place, but you don't know sh!t..
