It is the same core. More cache and quad-channel RAM are going to do almost nothing. Compare 1156 to 1366 - i7s at the same clocks perform almost identically. Triple-channel RAM didn't really help anything in gaming. Extra cache doesn't really help the i7-2600 over the i5-2500, either. SB-E isn't a new core. The overclocks it can achieve should be relatively close to other SBs.
