What are the advantages of a dual core processor? Im running a 3.4 Ghz pentium HT its clocked at 3.41 ghz and runs perfect. Im wondering if its worth it to upgrade to core 2 Duo. It seems that for the prices are high for 2.8 ghz core 2 duo What is the advantage of say a E6700 over clocked to 3.4 as opposed to just a 3.40 with HT clocked at 3.41 ghz Also Iv heard of some crazy clock speeds from core 2 duo, how high can these things be clocked? Any info would be greatly appreciated. Thanks.
