i'm about to receive an Intel 1.86 dual core laptop and i was wondering what i can expect in gains over my AMD 1.86 single core (2500xp). question: lets just say that they both contain 1 core. will this new processor be any more efficient than my old one? its been a long time since my 2500xp was made, is there anything to get excited about? Intel -- AMD 2mb L2 cache -- 512 KB 667MHz -- 333 MHz on a side note, even my video cards are about evenly matched. x1400 256mb and 9600pro.
