i know that 2600k is a quad core, PHYSICALLY, but its got hyper-threading, hence the "" around the 8.
correct me if i'm wrong but i didn't think that amd has HT so i thought it fair to compare intels 4(physical)+4(logical) core cpu with amds 8 physical core cpu (no HT)
again i'm not 100% about this, but its what i thought
if u guys are right, and they are cheaper then the intel counterpart i'll be building an AMD based machine later in the year
