Hey guys i was wondering if someone could explain why these are different and what cpu i could upgrade to preferably a dual core. i dont understand why it says 5000 mhz because it is supposed to be a 2.8 ghz single core. btw the bits with the ** are the parts i need help to understand.
Any help will be greatly appreciated
