i dont have alot but i saw something on ebay that interest me. it was a pc desktop manufacturer referbished that had a processor at 3 ghz but when i saw what the processor was it said "pc dual core 2" i was wondering because of the dual core, how can it be at 3ghz? i thought dual cores was slow at least for my laptop it is. is it different for desktop? also the one im looking for is in my price range so wanted input before i get.
